2006 Toyota Prius Complaint Log

I AM HAVING THE ISSUE REPORTED IN NHTSA ACTION NUMBER: PE09019. ISSUE WITH 2006 TOYOTA PRIUS EXTERIOR LIGHTING: HEADLIGHTS. SOMETIMES ONE OF MY HEADLIGHTS IS OFF OR IS DIM/FLICKERING. TURNING THE HEADLIGHTS OFF AND BACK ON FIXES THE PROBLEM MOST OF THE TIME. I RARELY USE MY HIGH BEAMS, BUT AROUND CHRISTMAS 2008 I WAS USING MY HIGH BEAMS AND WAS EITHER TURNING THEM OFF OR ON AND ALL MY HEADLIGHTS WENT OUT. I ALSO HAD MY FOG LAMPS ON AND CAN'T RECALL IF THEY WENT OUT AS WELL. TURNING THE HEADLIGHTS OFF AND ON BROUGHT BACK THE HEADLIGHTS. I'VE HAD THIS ISSUE WITH THE HEADLIGHTS ON AND OFF SINCE THAT TIME. *TR

BOTH HEADLIGHTS ON MY 2006 PRIUS GO OFF INTERMITTENTLY. WHEN I TURN THE HEADLIGHT SWITCH ON AND OFF THEY COME BACK ON (UNTIL THEY FAIL AGAIN). THIS HAS BEEN HAPPENING FOR OVER 6 MONTHS BUT WAS INFREQUENT AT FIRST. NOW THE FAILURES OCCUR ALMOST EVERY TIME I DRIVE THE VEHICLE. I UNDERSTAND THAT MANY PRIUS OWNERS HAVE THE SAME PROBLEM. SOME HAVE BEEN CHARGED AS MUCH AS $500 PER HEADLIGHT TO REPAIR. THIS IS NOT AN ORDINARY ISSUE OF REPLACING WORN OUT PARTS BUT IS CLEARLY A SAFETY RELATED ENGINEERING DEFECT. I AM TRYING TO GET TOYOTA TO REPAIR THIS WITHOUT CHARGE - BUT FROM WHAT I KNOW THERE SHOULD HAVE BEEN A RECALL TO FIX THIS PROBLEM. *TR

TL*THE CONTACT OWNS A 2006 TOYOTA PRIUS WHICH WAS PURCHASED IN DECEMBER 2008. WHEN THE HEADLIGHTS WERE TURNED ON, THE LEFT HEADLIGHT BECAME DIM AND SHUT OFF WITHIN 30 SECONDS. THE HEADLIGHTS REMAINED ON AFTER THEY WERE TURNED ON AND OFF CONTINUOUSLY; HOWEVER, THEY WOULD SHUT OFF AGAIN. THE PREVIOUS OWNER REPLACED THE HEADLIGHT ASSEMBLY AT 43,000 MILES. THE CONTACT IS AWARE OF THE SAFETY RISK WHILE DRIVING AT NIGHT WITHOUT HEADLIGHTS. THE DEALER QUOTED THAT THE REPAIR WOULD COST $560 TO REPLACE THE ENTIRE HEADLIGHT ASSEMBLY AGAIN. THE CURRENT AND FAILURE MILEAGES WERE APPROXIMATELY 82,500.

MY 2006 TOYOTA PRIUS WITH HID LIGHTS HAS A SERIOUS SAFETY ISSUE IN THAT AT ANY POINT WHILE I AM DRIVING, ONE OR BOTH OF THE HEADLIGHTS WILL FLICKER, DIM, AND EVENTUALLY TURN OFF. THE ONLY WAY THAT I CAN GET THE HEADLIGHTS BACK ON IS TO TURN THE HEADLIGHT SWITCH ALL THE WAY OFF, THEN TURN IT BACK ON AGAIN, CAUSING MY CAR TO BE WITHOUT HEADLIGHTS FOR AT LEAST TWO SECONDS EACH TIME I MUST DO THIS. AT TIMES, IT IS DIFFICULT TO NOTICE THAT ONE LIGHT HAS GONE OUT, AND ON MULTIPLE OCCASIONS, I HAVE FOUND MYSELF DRIVING WITHOUT ANY HEADLIGHTS AS THEY HAVE BOTH TURNED OFF DUE TO THIS ELECTRICAL/BULB FAILURE. I AM VERY AFRAID OF DRIVING AT NIGHT, AS AT LEAST ONE HEADLIGHT, IF NOT BOTH, WILL TURN OFF ABOUT EVERY THIRTY SECONDS. IT IS VERY DANGEROUS FOR THE HEADLIGHTS TO TURN OFF WITHOUT ANY WARNING. I HAVE CONTACTED TOYOTA AND THEY CLAIM THAT BULBS ARE NOT COVERED UNDER WARRANTY, SO THEY WILL NOT PAY TO FIX THE PROBLEM. THE DEALERSHIP HAS QUOTED ME AT $1,500 TO REPLACE THE BULBS AND COMPUTER ECU UNIT, WHICH IS AN EXORBITANT AMOUNT TO PAY FOR SOMETHING THAT IS CLEARLY DEFECTIVE AND VERY DANGEROUS. *TR

2006 TOYOTA PRIUS. BEGINNING AT APPROXIMATELY 45,000 MILES RIGHT FRONT HID HEADLIGHT WOULD GO OUT WITHOUT NOTICE. BY TURNING OFF THE HEADLIGHTS AND TURNING BACK ON, IT THE HEADLIGHT WOULD RELIGHT. STARTED INTERMITTENTLY, THEN CONSTANTLY UNTIL REPLACEMENT 11/3/09 ($200). ONE WEEK LATER, THE LEFT FRONT HEADLIGHT BEGAN DOING THE SAME THING. I DRIVE ON DARK, RURAL ROADS WITH DEER AND OTHER WILDLIFE. THIS DEFECT IS EXTREMELY DANGEROUS. HAVE READ NEWS REPORTS ABOUT HUNDREDS OF COMPLAINTS ABOUT THIS PROBLEM. *TR

I HAVE A 2006 TOYOTA PRIUS THAT SEEMS TO HAVE THE SAME BRAKING PROBLEM AS DESCRIBED FOR THE 2010 MODELS, WHEN I APPLY BRAKES ON A BUMPY OR ROUGH ROAD. I NOTICE IT MOST AT AN INTERSECTION IN MY TOWN - I HIT THE BRAKE PEDAL TO BEGIN SLOWING FOR A RED LIGHT, THE CAR STARTS TO SLOW, I HIT A PATCH OF ROUGH ROAD, THE CAR FEELS LIKE IT'S ACCELERATING (ITS RATE OF SLOWING IS LESS, SO IT FEELS LIKE IT'S ACCELERATING), THEN THE BRAKES "KICK IN" AGAIN AND SLOW THE CAR. VERY SURPRISING THE FIRST FEW TIMES IT HAPPENED BUT IN THREE YEARS IT'S HAPPENED SO OFTEN I HARDLY EVEN NOTICE IT. I DIDN'T ASSOCIATE IT WITH BUMPY ROADS UNTIL READING RECENT ARTICLES ON THE 2010 PRIUS BRAKE ISSUE. NO ACCIDENTS YET BUT I HESITATE TO LET OTHERS DRIVE MY PRIUS. THIS PROBLEM IS NOT LIMITED TO 2010 MODELS! I PUT JAN 1 2009 AS "APPROXIMATE INCIDENT DATE" BECAUSE YOU WON'T ACCEPT THIS FORM WITHOUT A SINGLE SPECIFIC DATE, BUT IT'S BEEN AN ONGOING PROBLEM WITH THIS CAR SINCE AT LEAST MARCH 2006 THROUGH JANUARY 2010. I HAVE NO IDEA IF THE CAR HAS ELECTRIC OR HYDRAULIC BRAKES SO I PICKED "SERVICE BRAKES HYDRAULIC". VERY UNCLEAR CATEGORY NAMES FOR "VEHICLE INFORMATION - DETAILS". *TR

ON MY 2006 TOYOTA PRIUS LEFT HEADLIGHT INTERMITTENTLY KEEPS GOING OUT. WHEN I TURN THEM ALL THE WAY OFF AND BACK ON THE LIGHT COMES BACK. *TR

IN 2006 I PURCHASED A 2006 TOYOTA PRIUS PACKAGE 6 WHICH INCLUDES HID (HIGH INTENSITY DISCHARGE) HEADLAMPS. STARTING APPROX. 1 YEAR AGO, I NOTICED A HEADLAMP OUT WHILE I WAS DRIVING. WHEN I TOOK IT TO THE DEALER I WAS TOLD IT WOULD COST $400+ TO REPAIR 1 HEADLAMP. AFTER DOING SOME RESEARCH ON THE INTERNET, I FOUND MANY COMPLAINTS ABOUT PRIUS HID HEADLAMPS. I ALSO FOUND OUT THAT IF YOU TURN THE LIGHT SWITCH OFF AND THEN ON, THEY WOULD WORK AGAIN TEMPORARILY, SO I DECIDED TO TOLERATE A HEADLAMP THAT IS PERIODICALLY OUT AND WOULD WORK AGAIN IF I TURNED THE SWITCH OFF AND ON. SOMETIMES THE DRIVER SIDE LIGHT WOULD BE OUT AND SOMETIMES THE PASSENGER SIDE LIGHT WOULD BE OUT. APPROX. 6 MONTHS AGO, I DISCOVERED THAT BOTH HEADLAMPS WOULD BE PERIODICALLY OUT WHILE I'M DRIVING, A REAL SAFETY PROBLEM. I STOPPED DRIVING AT NIGHT. APPROX. 2 WEEKS AGO, I RECEIVED A LETTER FROM TOYOTA THAT THEY RECOGNIZE THE PROBLEM AND WILL DISCOUNT THE HEADLAMP BULBS FROM $300 EACH TO $150 EACH PLUS LABOR. EVEN $150 IS TOTALLY OUTRAGEOUS BUT I NEEDED TO DRIVE THAT VEHICLE AT NIGHT SO I HAD BOTH LIGHTS REPLACED FOR A TOTAL OF $504.87. THERE SHOULD HAVE BEEN A RECALL FROM TOYOTA AND THEY SHOULD FIX THAT SAFETY PROBLEM FOR FREE. *TR

I HAVE 2006 PRIUS AND I HAVE BRAKE FAILURE FREQUENTLY IF I HIT A BUMP, POT HOLE, MANHOLE COVER, RAILROAD TRACK ETC. IT IS UN-NERVING AS I FEEL AS IF I AM AIRBORNE FOR A WHILE AS I KNOW I HAVE NO CONTACT WITH THE ROAD. *TR

I HAVE BEEN HAVING PROBLEMS WITH MY HEADLIGHTS GOING OUT FOR SEVERAL YEARS NOW. THIS IS THE SAME PROBLEM DESCRIBED BY OTHER DRIVERS WHEN THE LIGHTS GO OUT AND CAN BE RESET BY TURNING THEM OFF AND BACK ON AGAIN. FOR THE FIRST FEW YEARS, THE ONLY BULB TO GO OUT WAS THE RIGHT SIDE. THE BULB APPEARS TO HAVE NO BEARING ON THE PROBLEM. I HAVE PUT IN NEW BULBS AND HAD THE SAME PROBLEM. I EVEN TRIED SWITCHING THE NON-WORKING BULB WITH THE ONE THAT WAS WORKING ON THE LEFT SIDE. THE LEFT SIDE WORKED FINE LIKE THIS AND THE RIGHT SIDE CONTINUED TO FAIL. NOW, SEVERAL YEARS LATER, THE LEFT SIDE APPEARS TO BE FAILING ALSO. EVEN THOUGH I HAVE GOTTEN OTHER RECALL NOTICES, TOYOTA NEVER NOTIFIED ME OF A SETTLEMENT IN THIS CASE. AND, BY THE TIME THAT I FOUND OUT ABOUT IT, THE SETTLEMENT HAD EXPIRED. *TR

NO INJURIES YET, BUT WITH HEADLIGHTS CONTINUING TO GO OUT, IT IS ONLY A MATTER OF TIME. I JUST HOPE IT ISN'T ME OR MY KIDS. HTTP://WWW.HYBRIDCARS.COM/FORUMS/REPLACING-HEADLIGHT-BULB-T910.HTML. *TR

2006 TOYOTA PRIUS PACKAGE 6. HID LEFT HEADLIGHT INTERMITTENT FAILURE. WILL TURN BACK ON IF YOU CYCLE ON/OFF SWITCH. CAR HAS 57,000 MILES. PROBLEM MAY HAVE BEEN OCCURRING MUCH SOONER. HARD TO TELL UNLESS LOOKING AT HEADLIGHT REFLECTION IN CAR AHEAD OF YOU. SEVERAL PRIUSCHAT.COM MEMBERS HAVE REPORTED SAME PROBLEM. DIFFICULTY GETTING DEALER TO SOLVE OR COVER REPAIR. *TR

2006 TOYOTA PRIUS FRONT DRIVER SIDE HID HEADLIGHT TURNS OFF. IF I TURN THE LIGHTS OFF AND THEN BACK ON, THE HEADLIGHT COMES BACK ON AND FUNCTIONS PERFECTLY. THIS HAPPENS AT RANDOM OCCASIONS (DAY, NIGHT, SMOOTH ROADS, DRY, WET CONDITIONS), CHECKED CONNECTION AND ALL CONNECTIONS ARE FINE. *TR

HEADLIGHT/ELECTRICAL PROBLEM. ONE HEADLIGHT OUT INTERMITTENTLY STARTING IN MID-NOVEMBER. BOTH HEADLIGHTS WENT OUT ON 12/27/2008. WE PULLED OVER AND TURNED THE LIGHTS OFF AND WHEN WE TURNED THEM BACK ON BOTH RE-LIT. ON 1/2/2009 WE WERE PULLED OVER BY POLICE AND GIVEN A VERBAL SAFETY WARNING THAT ONE HEADLIGHT WAS OUT. LATER THAT EVENING, AFTER STOPPING THE CAR FOR A SHORT TIME BOTH LIGHTS CAME BACK ON. ON 1/5/2009, WE TOOK THE CAR TO THE DEALER WITH THE LEFT LIGHT OUT. WHEN THEY STARTED THE CAR THE NEXT DAY THEY FOUND BOTH LIGHTS TO BE WORKING. THEY INSPECTED ALL CONNECTIONS THEN FOUND THAT THE RIGHT LIGHT WAS OUT. THEY SAID IT WOULD COST $250 TO REPLACE THE BULB. WE CONTACTED TOYOTA AND ON 1/7/09 THEY OFFERED TO REPLACE THE RIGHT BULB FOR FREE. I DROVE HOME BEFORE MY WIFE AND AS SHE ARRIVED HOME I SAW ONE LIGHT OUT. UNFORTUNATELY, BY THE TIME I GOT OUT TO THE CAR, MY WIFE HAD SHUT IT OFF AND I COULD NOT RECALL WHICH ONE WAS OUT. WHEN WE RESTARTED THE CAR, BOTH LIGHTS CAME ON. *TR

INTERMITTENT BILATERAL HEADLIGHT FAILURE OF 2006 TOYOTA PRIUS. THE CAR HAS LESS THAN 30,000 MILES ON IT. WHEN LIGHTS ARE TURNED OFF AND ON QUICKLY THE FAILING LIGHT WILL COME BACK ON AGAIN. HOWEVER, THIS HAS ONLY PROVED TO BE A TEMPORARY SOLUTION SINCE BOTH HEADLIGHTS WILL RANDOMLY TURN OFF AGAIN AT A LATER TIME. *TR

I BELIEVE THAT I EXPERIENCED A BRAKE FAILURE. I WAS DRIVING ON A SNOWY LOCAL ROAD. I DO NOT KNOW MY EXACT SPEED, BUT I ESTIMATE IT WAS ABOUT 30 MPH (SPEED LIMIT IS 45 MPH). I SAW A CAR DRIVING SLOWLY IN FRONT OF ME AND I TRIED TO BRAKE FROM ABOUT HALF A BLOCK AWAY AND WAS UNABLE TO DO SO. I PUT MY FOOT ON THE PEDAL AS HARD AS I COULD BUT IT DIDN'T SEEM TO HAVE ANY EFFECT. BECAUSE I WAS UNABLE TO BRAKE, I ENDED UP HITTING THE CAR IN FRONT OF ME. AFTER THE ACCIDENT, I DISTINCTLY REMEMBER LOOKING AT MY FEET TO CONFIRM THAT I HAD MY FOOT ON THE BRAKE AND NOT THE ACCELERATOR, AND I HAD, INDEED, HAD MY FOOT ON THE CORRECT PEDAL. THERE WAS LITTLE DAMAGE TO THE OTHER CAR (MOSTLY A BROKEN FENDER, I BELIEVE). MY CAR EXPERIENCED CONSIDERABLE DAMAGE TO A HEADLIGHT, WHEEL, DOOR AND A BIT TO THE ENGINE, BUT WAS REPAIRED. THE SERVICE TECHNICIAN SHOWED ME THAT MY FRONT TIRES WERE A BIT LOW ON TREAD (BUT NOT COMPLETELY BALD). THE REAR TIRES HAD BEEN CHANGED WITHIN THE LAST TWO MONTHS. *TR

MY WIFE ALMOST HIT A TRIO OF PEDESTRIANS WHO WERE WALKING IN THE ROAD, AND WHO WERE VERY POORLY LIT BY THE 2006 PRIUS HEADLIGHTS. THESE HEADLIGHTS (LOW BEAMS) ARE ALWAYS EXTREMELY DIM AND IN MY OPINION ARE UNSAFE TO DRIVE WITH AT NIGHT. HIGH BEAMS SEEM TO LIGHT THE ROAD ADEQUATELY. THIS PROBLEM IS NOT CAUSED BY INTERMITTENT OPERATION OF THE HEADLIGHTS (A PROBLEM WE'VE ALSO DEALT WITH), BUT IS CAUSED BY THE FACT THAT THE HEADLIGHTS DO NOT PROVIDE ADEQUATE ILLUMINATION OF THE ROAD. WE ALSO DRIVE A 2005 ACURA TL AND A 2004 TOYOTA SIENNA AND BOTH OF THESE VEHICLES PROVIDE GOOD ILLUMINATION OF THE ROAD AT NIGHT. A VEHICLE DRIVING BEHIND OUR 2006 PRIUS WILL OFTEN CAST A SHADOW OF OUR CAR IN THE AREA IN FRONT OF THE CAR, IN THE AREA THAT'S SUPPOSED TO BE ILLUMINATED BY THE HEADLIGHTS. I'M SURPRISED THAT THERE'S NO RECALL ON THIS VEHICLE AND THAT TOYOTA HASN'T RECTIFIED THIS PROBLEM, WHICH IN MY OPINION MAKES THE VEHICLE EXTREMELY UNSAFE TO DRIVE AT NIGHT. *TR

2006 TOYOTA PRIUS HEADLAMP GOES OUT INTERMITTENTLY, TURNING LIGHTS OFF THEN BACK ON TEMPORARILY FIXES PROBLEM. SINCE PROBLEM IS INTERMITTENT IT IS IMPOSSIBLE TO KNOW IF FRONT LIGHTS ARE WORKING. *TR

DRIVING AT NIGHT, THE PASSENGER SIDE HEADLIGHT SOMETIMES GOES OUT, SOMETIMES WORKS. I WOULD SAY IT WORKS 25% OF THE TIME. THIS RESULTS IN LIMITED VISIBILITY WHEN DRIVING AT NIGHT. AT THIS POINT, NOTHING HAS BEEN DONE TO CORRECT THE FAILURE BECAUSE THE HEADLIGHTS ARE VERY EXPENSIVE AND SO FAR THERE HAS NEVER BEEN A TOTAL LOSS OF VISIBILITY. *TR

DRIVERS SIDE HEADLIGHT GOES OUT AFTER BEING ON 1ST. AFTER THE HEADLIGHTS ARE ON, THE LEFT(DRIVERS SIDE) HEADLIGHT SIMPLY GOES OFF. IF I TURN THE HEADLIGHTS OFF AGAIN, THEY BOTH COME BACK ON, AND THEN AGAIN, THE DRIVERS SIDE HEADLIGHT GOES BACK OFF. PRIOR TO THIS ISSUE, BOTH HEADLIGHTS WOULD GO OFF, I WOULD TURN BOTH HEADLIGHTS OFF, BACK ON AND THEY'D BE FINE FOR A LITTLE WHILE, AND THE CYCLE OF OFF AND ON, ON AND OFF WOULD CONTINUE! *TR

STANDARD HEADLIGHT FAILURE IN A 2006 TOYOTA PRIUS. I'VE REPLACED 4 SETS OF BULBS SINCE DECEMBER 2008. THE BULBS FAIL IN NORMAL OPERATION, TYPICALLY THE LOW BEAM FAILS FIRST, THEN THE HIGH BEAM. GENERALLY BOTH BULBS FAIL WITHIN A FEW HOURS OF EACH OTHER. I'VE HAD HE CAR TO THE DEALER TWICE FOR THIS PROBLEM. THE FIRST TIME, THEY COULD FIND NO PROBLEM. THE SECOND TIME - TODAY - THEY SAY THE SYLVANIA SILVERSTAR BULBS I'VE BEEN USING AREN'T TOYOTA PARTS SO THAT'S THE PROBLEM, NOT THE CAR. I WAS CONVINCED THIS IS DEFECT IN THE VEHICLE THAT THE DEALER JUST CAN'T BE BOTHERED TO IDENTIFY, BUT AFTER A BRIEF GOOGLE SEARCH I FOUND THAT I AM NOT ALONE. MOST COMPLAINTS INVOLVE HID SYSTEMS, BUT THERE ARE NUMEROUS POSTED COMPLAINTS INVOLVING THE STANDARD HEADLIGHT SYSTEM INSTALLED ON MY CAR. THIS IS A SERIOUS SAFETY DEFECT AND IT WILL LEAD TO SERIOUS INJURY AND/OR DEATH IF IT IS NOT INVESTIGATED AND CORRECTED QUICKLY. PLEASE INTERVENE ON MY BEHALF AND ON THE BEHALF OF ALL THE OTHER PRIUS OWNERS WHO ARE GETTING NO SUPPORT FROM TOYOTA IN RESOLVING THIS DEFECT. *TR

OUR 2006 TOYOTA PRIUS (60,000 MILES) HAS A DEFECTIVE FRONT HEAD LIGHT WHICH FLICKERS AND GOES OUT UNTIL I TURN THE LIGHT SWITCH ON AND OFF, WHICH THEN KEEPS IT ON FOR A SHORT TIME. REPAIR COST HAS BEEN ESTIMATED AT $1000.00. I HAVE BEEN TOLD THAT THIS IS A COMMON PROBLEM, BUT TOYOTA HAS NOT RECALLED THEIR PRIUS YET. THEY DO NOT WARRANTY THE REPLACEMENT PART. THIS CAN CAUSE AN EXTREME HAZARD TO DRIVING ON UN-LIT ROADS. THE BULB ON THE PASSENGER SIDE FLICKERS AND GOES OUT WITHIN MINUTES OR WILL STAY ON 15 MINUTES OR SO. AS OF THIS POINT I HAVE BEEN UNABLE TO AFFORD THE COST TO REPLACE BULB. *TR

HID BULB INTERMITTENTLY SHUTS OFF IN MY 2006 TOYOTA PRIUS. TOYOTA WANTS TO REPLACE BULB ($162.50 EACH). HOWEVER, ACCORDING TO THE BLOGS, THIS IS A RECURRING PROBLEM WITH PRIUS'S AND MAY BE A "CONTROLLER" PROBLEM, NOT A BULB ISSUE. *TR

NHTSA PE09019 - 2006 PRIUS, HAVE HAD 1 PASSENGER AND THREE DRIVER'S SIDE HID BULBS FAIL WITHIN 6 MONTHS. *TR

THE FRONT HID HEADLIGHTS ON MY 2006 PRIUS PERIODICALLY GO OFF, WITH NO EXPLANATION -- BOTH THE RIGHT AND LEFT SIDE HAVE FAILED ON OCCASION, BUT NEVER AT THE SAME TIME. IF I TURN THE LIGHTS OFF AND THEN BACK ON AGAIN, THE LIGHT COMES BACK ON. THIS HAS BEEN OCCURRING OVER A NUMBER OF MONTHS, SO TODAY I HAD IT ANALYZED AND WAS TOLD THE HID COMPUTER FOR EACH OF THE LIGHTS IS OK, BUT THE LIGHT BULBS THEMSELVES NEEDED TO BE REPLACED, WHICH I DID AT A COST OF OVER $200 PER BULB. I WAS TOLD AT THE DEALER THAT THEY'VE HAD NUMEROUS COMPLAINTS ABOUT THIS, BUT WERE NOT AWARE OF ANY FACTORY AUTHORIZED REPAIR OF SAID PROBLEM. AFTER READING AN INTERNET BLOG ON THIS ISSUE, AND HEARING OF NUMEROUS IDENTICAL COMPLAINTS, I'M CONVINCED TOYOTA OUGHT TO BE HELD ACCOUNTABLE FOR THIS SERIOUS AND POTENTIALLY DANGEROUS PROBLEM. *TR

OUR 2006 TOYOTA PRIUS HAS A HEADLIGHT THAT WILL RANDOMLY TURN OFF WHILE DRIVING. IT IS VERY DIFFICULT TO TELL WHEN A HEADLIGHT TURNS OFF. IF WE DO REALIZE THAT THE HEADLIGHT HAS TURNED OFF, WE CAN TURN BOTH HEADLIGHTS OFF WHILE DRIVING AND THEN TURN THEM BACK ON. THIS "RESETS" THE LIGHTS AND THEY BOTH COME BACK ON. LIVING IN THE COUNTRY WHERE ROADS ARE VERY WINDY AND ILLUMINATED STREETS ARE UNCOMMON, THIS IS A SERIOUS SAFETY ISSUE. THE DEALER CLAIMS THEY ARE BAD BULBS; HOWEVER, THE HID BULBS SHOULD LAST 8-10 YEARS. OUR BULB HAS LASTED ONLY 2.5 YEARS. TO REPLACE THE BULB IT COSTS OVER $500, WHICH IS RIDICULOUS. THERE ARE OBVIOUS SAFETY PROBLEMS WITH BULBS RANDOMLY GOING OUT WHILE DRIVING. BASED UPON DISCUSSIONS WITH OTHER PRIUS OWNERS, THIS IS A COMMON PROBLEM. OTHER HAVE BEEN CHARGED UPWARDS OF $1800 TO CHANGE BOTH HEADLAMPS ON CARS UNDER 50K MILES. SOMETHING SHOULD BE DONE TO MAKE TOYOTA RECOGNIZE THIS SIGNIFICANT SAFETY RISK. *TR

2006 TOYOTA PRIUS. PASSENGER LIGHT (BOTH LOW AND HIGH BEAMS) INTERMITTENTLY GOES OUT. TURNING CAR OFF AND BACK ON OFTEN BRINGS LIGHT BACK ON. TOYOTA DEALER HAS HAD OTHER COMPLAINTS AND RECOMMENDS REPLACING HEADLIGHT (ONE HEADLIGHT IS NEARLY $400, WITH LABOR IT IS NEARLY $500). I'VE ALWAYS BEEN TOLD TO REPLACE HEADLIGHTS IN PAIRS WHICH MAKES THAT $1000 REPAIR WHEN CLEARLY THE HEADLIGHTS ARE FAILING WIDELY AND I SUSPECT PREMATURELY. THIS IS WIDELY REPORTED IN PRIUSCHAT AND OTHER INTERNET USER GROUPS AND NO ONE HAS IDENTIFIED THE ROOT CAUSE. SURELY THERE AREN'T *THIS* MANY BAD BULBS. IF IT IS A COMPUTER PROBLEM IT COULD LEAD TO OTHER FAILURES. THIS IS A SAFETY ISSUE! TOYOTA NEEDS TO INVESTIGATE THE CAUSE AND OFFER A RECALL SOLUTION. IT APPEARS THAT COMPLAINTS THROUGH THIS WEBSITE ARE INCREASINGLY FREQUENT. THANKS! *TR

I WAS STOPPED IN 2006 PRIUS BY STATE TROOPER FOR HEADLIGHT OUT ON PASSENGER SIDE. LOCAL DEALER TOLD ME NEW HID LAMPS WILL COST $350 WITHOUT INSTALLATION. I ORDERED THEM AND THEN FOUND OUT THAT THE LAMPS SHOULD LAST AT LEAST 10 YEARS AND THAT THE PROBLEM AFFECTS MOST PRIUS CARS WITH HID HEADLIGHTS FROM 20,000 TO AROUND 50,000 MILES AND THAT TOYOTA IS WELL AWARE OF THE PROBLEM BUT HAS NOT ISSUED A DEFECT RECALL TO DATE. THE FAILURE APPEARS TO BE RANDOM AND THE LAMPS WILL RE-START WHEN SWITCHED OFF AND BACK ON AGAIN. SINCE THE LAMPS EXTINGUISH RANDOMLY, THERE IS THE POSSIBILITY OF BOTH FAILING SIMULTANEOUSLY WITH SERIOUS SAFETY ISSUES. *TR

2006 TOYOTA PRIUS HID HEADLIGHTS HAVE REPEATEDLY FAILED. BOTH HEADLIGHTS INTERMITTENTLY FAILED AND WERE REPLACED BY TOYOTA 11/24/07. NOW R HID HEADLIGHT HAS FAILED AGAIN. LOSS OF HEADLIGHTS CREATES A MAJOR SAFETY HAZARD. *TR

1. NO SPECIAL EVENT LED TO FAILURE. FIRST FAILURE OCCURRED AT ABOUT 35,400 MILES (ODOMETER). 2. TWO HEADLIGHTS GO OUT SIMULTANEOUSLY WHILE DRIVING ON AN INTERMITTENT BASIS. EACH HEADLIGHT CAN ALSO GO OUT WHILE DRIVING INDEPENDENTLY OF THE OTHER. 3. POWERING OFF /ON THE CAR RESOLVES THE PROBLEM. TURNING THE HEADLIGHTS OFF AND ON AGAIN SOLVES THE PROBLEM. THE REPAIR SHOP (DEALER) COULD NOT RECREATE THE PROBLEM AND SO DID NOT REPLACE ANY PARTS AT MY FIRST VISIT. I AM ABOUT TO GO BACK AND TRY AGAIN. *TR

HIGH INTENSITY HEADLIGHT PROBLEM ON 2006 PRIUS. LIGHT GOES OFF INTERMITTENTLY. SOMETIMES WILL COME BACK ON AFTER FLICKING ON AND OFF A FEW TIMES. SOMETIMES WILL NOT COME ON AT ALL. REPLACED PASSENGER SIDE AT AROUND 26,000 MILES AND DRIVER'S SIDE A FEW MONTHS LATER. COVERED BY WARRANTY THOSE TIMES. NOW AT 53,000 PASSENGER SIDE IS OUT AND DEALER IS CHARGING $300.00 TO REPLACE HEADLIGHT. DEALER STATED THAT THEY HAVE HAD MANY OTHER CUSTOMERS WITH SAME PROBLEM. AS OF TODAY THERE IS NO RECALL. *TR

I HAVE A 2006 TOYOTA PRIUS THAT HAS AN INTERMITTENT FRONT LEFT HEADLIGHT. IT GOES ON WHEN I FIRST START IT AND THEN IT GOES OFF A FEW MINUTES LATER. IF YOU REDO THE HEADLIGHT IT GOES ON THEN SHUTS OFF AGAIN. IT SEEMS VERY DANGEROUS AND THE DEALER IS SAYING IT WILL COST OVER $200 TO FIX. *TR

PASSENGER SIDE HEADLIGHT FADES THEN GOES OUT. TURNING THE SWITCH OFF/ON WILL TURN THE HEADLIGHT ON AGAIN - SOMETIMES IT WILL FADE OUT AGAIN, SOMETIMES IT WILL STAY ON. DEALERSHIP SWITCHED THE BULBS (PASSENGER TO DRIVER SIDES) TO SEE IF IT'S A BULB PROBLEM OR SOMETHING ELSE. NOW THE DRIVER'S SIDE (SAME BULB) IS DISPLAYING THE SAME SYMPTOMS. HAVE NOT YET REPLACED THE BULB DUE TO THE HIGH COST. *TR

1. NORMAL OPERATING CONDITIONS 2. PASSENGER OR DRIVER SIDE HEADLAMP GOES OUT. INTERMITTENTLY 3. BULB REPLACEMENT. *TR

AFTER ABOUT 40,000 MILES, THE DRIVER'S SIDE HEADLIGHT IN MY 2006 TOYOTA PRIUS STARTED BLINKING OFF (I.E., IT WOULD TURN OFF, BUT THEN IF I SWITCHED THE LIGHTS ON AND OFF, IT WOULD BE ON AGAIN). *TR

MY 2006 TOYOTA PRIUS EXPERIENCES INTERMITTENT, SPORADIC EVENTS IN WHICH THE HEADLAMPS (BOTH OF THEM BUT NOT SIMULTANEOUSLY) GO OUT. THERE IS NOTHING TO PREDICT WHICH ONE WILL GO OUT, AT WHICH TIME AND THIS MORNING AT 6:35 AM THE DRIVER'S SIDE WENT OUT AS WELL AS THE PASSENGER SIDE, LEAVING ME DRIVING IN THE PITCH DARK. I HAD THE DRIVERS SIDE HEADLAMP REPLACED AFTER HOURS OF A TOYOTA TECH NOT BEING ABLE TO FIND ANYTHING WRONG WITH THE WIRING. I HAVE BEEN PULLED OVER ON SEVERAL OCCASIONS ONLY TO TURN OFF MY LIGHTS AND TURN THEM BACK ON AT WHICH POINT THE LIGHTS COME ON AGAIN. THIS IS SAFETY ISSUE FOR ME AS I DRIVE APPROX 30000 MILES A YEAR AND CANNOT BE LIMITED TO DRIVING IN DAYLIGHT HOURS. TOYOTA HAS BEEN UNABLE TO DIAGNOSE THE PROBLEM (OR IDENTIFY IT) FOR ME AND I REFUSE TO CONTINUE TO REPLACE HEADLAMPS, ESPECIALLY AT SUCH A HIGH PRICETAG. THIS HAS BEEN AN ONGOING ISSUE WITH THE LATEST INCIDENT HAPPENING TODAY. I AM TIRED OF THIS. *TR

HID HEADLIGHT HAS BEGAN FAILING AFTER ONLY 45,000 MILES. IF I TURN OFF THE CAR AND TURN IT BACK ON, THE HEADLIGHT COMES BACK ON. IT IS AN INTERMITTENT ISSUE. THE DEALER HAS TOLD ME THAT I NEED TO HAVE THE BULB REPLACE ALREADY AND IT IS NOT COVERED UNDER THE TOYOTA EXTENDED WARRANTY. THEY WANT ALMOST $500 TO REPLACE ONE HID BULB! THERE MUST BE A PROBLEM WITH TOYOTA'S SUPPLY OF HID BULBS! THERE IS NO WAY THAT PEOPLE CAN AFFORD TO PAY 500 EVERY 45,000 MILES TO REPLACE ONE HEADLIGHT! THESE THINGS ARE SUPPOSED TO LAST FOR MANY YEARS AND I'VE ONLY HAD MY CAR FOR JUST OVER TWO YEARS. IS THERE ANYTHING YOU CAN DO TO HELP WITH THIS? THERE ARE HUNDREDS OF COMPLAINTS ON THE INTERNET FROM OTHER PRIUS OWNERS EXPERIENCING THIS SAME PROBLEM. THANK YOU. *TR

PASSENGER SIDE HEADLAMP CEASED WORKING AFTER SEVERAL MINUTES OF DRIVING. THE LAMP RETURNS TO NORMAL OPERATION AFTER THE LIGHT SWITCH IS CYCLED OFF AND THEN BACK ON. THIS PROBLEM HAS RECURRED THREE TIMES. *TR

EVER SINCE I PURCHASED MY 2006 TOYOTA PRIUS, I HAVE HAD INTERMITTENT PROBLEMS WITH THE BRAKES LETTING UP FOR A COUPLE SECONDS WHEN GOING AT SLOW SPEEDS (UNDER 25 MPH) AND HITTING A BUMP OR SHALLOW HOLE WHEN BRAKING. TYPICALLY, THE ANTI-SKID (VSC) LIGHT COMES ON FULLY OR FLICKERS FOR SEVERAL SECONDS AND THE CAR MOMENTARILY STOPS BRAKING (YOU CAN FEEL THE CAR ACCELERATE FORWARD SLIGHTLY AND THE PEDAL FEELS LIKE IT IS ON THE FLOOR). IT DOES NOT SEEM RELATED TO WET OR DRY CONDITIONS AS IT HAS HAPPENED IN BOTH. BUT IT DOES SEEM TO BE RELATED TO GOING OVER A SMALL BUMP OR EVEN MORE FREQUENTLY WHEN HITTING A SMALL POTHOLE/SEWER PLATE WHILE BRAKING. IF I HAVE THE REACTION TIME & FORETHOUGHT, IMMEDIATELY LETTING GO OF THE BRAKE PEDAL COMPLETELY AND PRESSING DOWN HARD WILL GET THE CAR TO STOP. FORTUNATELY, IT HAS HAPPENED ENOUGH TIMES (INCLUDING SEVERAL NEAR MISSES) THAT I ALLOW EXTRA DISTANCE WITH CARS IN FRONT OF ME AND BEEN LUCKY TO AVOID COLLISIONS. I ALSO WATCH THE ROAD SURFACE FOR BUMPS/HOLES WHEN BRAKING BUT AM WORRIED THAT I MIGHT NOT BE LUCKY TO AVOID 100% OF THE TIME AND COULD REAR END A CAR OR EVEN WORSE I COULD SERIOUS INJURE A PEDESTRIAN WALKING ACROSS A CROSSWALK AS I'M COMING TO A STOP AT A RED LIGHT. I HAVE HAD THE CAR INTO MY DEALERSHIP TWICE AND THEY HAVE TRIED TO REPLICATE IT BUT HAVEN'T BEEN ABLE TO SO THEY HAVEN'T DONE ANYTHING ABOUT IT. IF YOU CHECK OUT THIS FORUM, YOU WILL SEE THAT I AM DEFINITELY NOT ALONE HOWEVER: HTTP://WWW.HYBRIDCARS.COM/FORUMS/BRAKE-FAILURE-2007-T1013.HTML. *TR

MY PASSENGER SIDE HEADLIGHT WAS REPORTED TO BE OUT BY MY HUSBAND SO I TOOK THE CAR TO THE DEALERSHIP. THE LIGHT WAS WORKING FOR THEM, THEY TOLD ME AT THAT TIME IT WOULD BE $600 TO REPAIR SO I SHOULD WAIT UNTIL "IT IS A REAL PROBLEM" BEFORE FIXING IT. WITHIN A WEEK OR TWO I WAS PULLED OVER BY A STATE TROOPER FOR HAVING A HEADLIGHT OUT. FORTUNATELY FOR ME, HE ONLY ISSUED A WARNING. I TOOK THE CAR BACK TO THE DEALERSHIP, AND THE WOMAN BOOKING ME IN SAID "OH YEAH, WE SEE THAT PROBLEM WITH THE PRIUS". I ASKED "WHAT PROBLEM, EXACTLY IS THAT PROBLEM?" SHE SAID "JUST WHAT YOU REPORT, HEADLIGHTS GOING OUT & COMING BACK ON AGAIN". I ASKED IF THAT SHOULD BE A RECALL, AND SHE SAID "YOUR CAR IS NO LONGER UNDER WARRANTY, BUT I'LL SEE WHAT I CAN DO FOR YOU." ULTIMATELY, THEY REPLACED BOTH HEADLIGHTS AND THE COMPUTER THAT IS ASSOCIATED WITH EACH HEADLIGHT & THE DEALERSHIP ABSORBED THE COST "AS A GOODWILL GESTURE & BECAUSE OF OWNER LOYALTY". SEEMS TO ME THEY KNOW THERE IS A DEFECTIVE PART AND THEY ARE TRYING TO DUCK A RECALL. *TR

2006 TOYOTA PRIUS HID HEADLIGHT FAILS INTERMITTENTLY WITHOUT WARNING. HEADLIGHT CANNOT BE REPAIRED BY NORMAL MEANS REQUIRING THE VEHICLE BY DRIVEN UNSAFELY OR ABANDONED ON THE ROAD UNTIL IT CAN BE TOWED. HEADLIGHTS NON AVAILABILITY THROUGH NORMAL SUPPLIERS ENCOURAGES OWNERS TO DRIVE WITHOUT THE HEADLIGHT (S). ADDITIONALLY, REPAIR COSTS CAN EASILY EXCEED $1000 FOR A HEADLIGHT.TR

RIGHT HEADLIGHT TURNS OFF INTERMITTENTLY. TURNING THE SWITCH OFF AND ON WITH TURN THE HEADLIGHT BACK ON. AFTER A SHORT PERIOD OF TIME IT WILL SHUT OFF AGAIN. *TR

2006 TOYOTA PRIUS PURCHASED FROM BEAMAN TOYOTA IN NASHVILLE, TENNESSEE, FEBRUARY ?06 (EVEN THOUGH TOYOTA SAYS THE DELIVERY DATE WAS NOVEMBER ?05) AT APPROXIMATELY 25000 MILES, THE DRIVER SIDE HIGH INTENSITY HEADLIGHT BEGAN TO GO OUT WHEN I WAS DRIVING, I COULDN'T SEE IT. I WOULD SEE THAT IT WAS OUT IN THE REFLECTION OF THE TRUNK LID OF ANOTHER VEHICLE. IF I SIMPLY TURN THE LIGHT SWITCH OFF AND BACK ON THE LIGHT WOULD COME BACK ON AND WOULD NOT GO OFF FOR A WHILE. AT FIRST, IT ONLY HAPPENED SPORADICALLY, BUT OVER SOME MONTHS GOT MUCH WORSE. I TOOK IT TO A DEALER, THEY REPLACED THE BULB. THEY SAID IT WAS UNDER WARRANTY AND THE $430 WAS COVERED. $430 FOR A HEADLIGHT BULB??????? THEY SAID THEY HAD TO TAKE THE BUMPER OFF THE CAR TO GET TO THE BULB. I LET THAT PASS, BUT THEN THE PASSENGER SIDE HEADLIGHT DID THE SAME THING. AGAIN, IT WAS SPORADIC. IN OCTOBER ?08 IT BEGAN TO CAUSE A REAL PROBLEM. I COULD NOT DRIVE MORE THAN A MILE WITHOUT IT GOING OUT. ON NOVEMBER 14, 2008, I TOOK IT BACK TO THE DEALER. AGAIN IT WAS A BAD BULB. I HAVE WATCHED THIS PROBLEM FOR QUITE A WHILE AND I DO NOT BELIEVE IT IS THE BULB. EVEN THOUGH I HAD PURCHASED THE 100,000 MILE BUMPER-TO-BUMPER WARRANTY, NAIVELY THINKING IT WOULD TAKE CARE OF THINGS LIKE THIS, I WAS TOLD IT WOULD COST $535 AND THAT I WOULD HAVE TO PAY OUT OF POCKET BECAUSE IT WAS CONSIDERED ?MAINTENANCE? AND WAS NOT COVERED UNDER WARRANTY. $535 FOR A HEADLIGHT BULB????????MAINTENANCE???????? WHAT IF BOTH HEADLIGHTS GO OUT WHILE DRIVING AT NIGHT??????? IF I LIVE, YOU KNOW WHO I?M GOING AFTER. BUT, NOT ONLY IS THIS A SAFETY ISSUE AND JUST PLAIN WRONG, THIS IS A REALLY POOR DESIGN. I KNOW TOYOTA HAS TO MAKE A PROFIT, AND EVERYONE ELSE WHO EVEN BREATHS ON THIS BULB HAS TO MAKE A PROFIT. BUT, THIS IS EXORBITANT AND I CONSIDER IT GOUGING. I ALSO FOUND I COULD BUY THIS BULB ON THE INTERNET FOR $108. WHY HAS TOYOTA NOT ADDRESSED THIS PROBLEM ?? THIS IS A SERIOUS SAFETY ISSUE. *TR

2006 TOYOTA PRIUS, 49,800 MILES HID HEAD LIGHT FAILED. *TR

ONE OF THE HEADLIGHTS KEEPS GOING OUT. I CAN'T REALLY TELL WHEN OR HOW IT GOES OUT SINCE I CAN'T SEE IT. I'LL NOTICE IT WHEN I SEE THE REFLECTION IN THE BACK OF ANOTHER CAR. IF I TURN THE BRIGHT LIGHTS ON AND OFF IT HAS NO EFFECT, BUT WHEN I TURN THEM ALL THE WAY OFF AND BACK ON THE LIGHT COMES BACK. SOMETIMES ON LONG TRIPS IT WILL STAY ON THE WHOLE TIME, SOMETIMES IT WON'T. SOMETIMES ON SHORT TRIPS IT WILL GO OUT, SOMETIMES IT WON'T. IT IS NOT AN EVENT I CAN MAKE HAPPEN. I'VE TAKEN IT TO THE DEALER AND THEY CAN'T MAKE IT HAPPEN (OF COURSE). THIS HAS BEEN GOING ON FOR OVER 1 YEAR. *TR

DRIVER SIDE HEADLIGHT GOES OUT INTERMITTENTLY, GOES BACK ON IF I SHUT LIGHTS OFF AND TURN BACK ON. DEALER SAYS BULB IS BAD, NOT COVERED ON REGULAR OR EXTENDED WARRANTY. THIS IS A SERIOUS SAFETY ISSUE. THIS HAS BEEN GOING ON FOR SEVERAL MONTHS. *TR

I HAVE A 2006 TOYOTA PRIUS WITH ABOUT 60,000 MILES. I AM EXPERIENCING THE WIDELY REPORTED ISSUE WITH THE HID HEADLIGHT. THE DRIVER SIDE HEADLIGHT FAILS TO TURN ON SOMETIMES, BUT IF I NOTICE IT AND TURN OFF THE HEADLIGHTS AND TURN THEM BACK ON, THE PROBLEM GOES AWAY. EVEN IF THE LIGHT WORKS, IT SOMETIMES FLICKERS AND GOES OUT AFTER A FEW MINUTES. I GOT PULLED OVER BY THE POLICE TONIGHT FOR A FAILED HEADLIGHT. SINCE THIS SEEMS TO BE A WIDELY REPORTED ISSUE, TOYOTA SHOULD FIX THIS FOR THE PEOPLE WHO HAVE ENCOUNTERED IT. THANKS! *TR

2006 TOYOTA PRIUS - HEADLIGHT (HID) FAILURE. STARTED WITH LEFT HEADLIGHT (PASSENGER SIDE) AT ABOUT 40,000 MILES, THEN RIGHT HEADLIGHT BEGAN TO FAIL AT ABOUT 45,000 MILES. HEADLIGHTS FLICK OFF WHILE DRIVING. ONE OR BOTH FLICK OFF AT ANY TIME. CAN TURN BACK ON BY TURNING HEADLIGHTS COMPLETELY OFF, THEN TURNING BACK ON. BUT AFTER A FEW MINUTES, DECREASE IN INTENSITY AND FLICK OFF AGAIN. TOYOTA DEALER HAS ADVISED THIS IS "NORMAL", THAT THE LIGHTS HAVE A HEAT SENSOR AND TURN OFF WHEN THEY OVERHEAT, AND THAT I NEED TO REPLACE BOTH HEADLIGHT ASSEMBLIES. *TR

I HAVE A 2006 PRIUS WITH HEADLIGHT PROBLEMS. ONE WILL GO OFF FOR NO REASON. IF YOU TURN THE LIGHTS OFF AND ON THE LIGHT THEN WORKS. THIS HAPPENS TO BOTH SIDES AND ONLY A FEW TIMES HAVE I LOST BOTH LIGHTS AT THE SAME TIME. VERY UNSAFE. I HAVE THE HID PACKAGE AND SEE THAT THERE ARE OVER 60 OTHER COMPLAINTS. TOYOTA NEEDS TO FIX THIS PROBLEM BEFORE SOMEONE GETS KILLED. I HAVE BEEN DEALING WITH THIS FOR MORE THAN A YEAR. THE DEALER HAS NO INFORMATION FROM TOYOTA ABOUT THIS PROBLEM. PLEASE HELP! *TR

HEADLIGHT FAILURE AT RANDOM TIMES ON MY 2006 TOYOTA PRIUS WITH HID HEADLIGHTS. LIGHTS ALWAYS WORK CORRECTLY WHEN FIRST TURNED ON. DURING TRIPS OF 15-30 MINUTES, ONE HEADLIGHT USUALLY FAILS. THE LEFT GOES OUT MORE OFTEN THAN THE RIGHT. WHEN FAILED, NEITHER THE DIM NOR BRIGHT WILL WORK. FUNCTION IS RESTORED BY TURNING THE HEADLIGHT SWITCH OFF AND THEN BACK ON. HAVE HAD SEVERAL DANGEROUS MOMENTS WHEN LEAVING BRIGHTLY-LIT STREETS, MAKING TURNS ONTO DARK ENTRANCE RAMPS. SUDDENLY, THE ABSENCE OF EXPECTED HEADLIGHTING IS OBVIOUS WHILE SCANNING IN THE DARKNESS FOR THE CURBS, EDGE OF THE ROAD, ETC. IT TOOK ME SOME TIME TO DIAGNOSE THE PROBLEM AS UPON STARTUP, BOTH HEADLIGHTS ALWAYS WORK CORRECTLY. I NOW BELIEVE THE PROBLEM IS IN THE HEADLIGHT CONTROL CIRCUITS, NOT IN THE BULBS, AS MUCH OF THE TIME, BOTH RIGHT AND LEFT HEADLIGHTS, DIM AND BRIGHT, WORK FINE. *TR
