Open the full vehicle complaint log (all categories)I READ AN ARTICLE TODAY IN THE DETROIT FREE PRESS WHICH HAS PROMPTED ME TO WRITE YOU REGARDING HIDDEN LAMPS. MY COMPLAINT IS GENERAL, IN THAT THE AMOUNT OF "DAZZLE" FROM THE SCATTERED LIGHT IS GREATLY OBJECTIONABLE, AND MUST BE CONTROLLED. "HEAD-ON" VIEWING OS ACCEPTABLE, BUT SLIGHT OFF-ANGLE IS EXTREMELY DISTRACTING AND PAINFUL FROM THESE LAMPS. I WORK FOR A MAJOR AUTO COMPANY, AND HAVE SOME EXPERIENCE IN LIGHTING TECHNOLOGY. I WOULD PREFER IF NHTSA MIGRATE TO EUROPEAN REQUIREMENTS (CUT-OFF LINES) AND ENFORCE SOME TYPE OF ANTI-DAZZLE REQUIREMENTS FOR THESE LAMPS. ALTHOUGH ALLOWING A "WASH" IN FRONT OF THE VEHICLE ON THE ROAD, THE SIDE SCATTER I BELIEVE IS MORE DANGEROUS, POSSIBLE CAUSING OR RELATING TO ONCOMING DRIVER IRRITATION, ROAD RAGE, OR POSSIBLE ACCIDENTS. *AK
THE HIGH BEAM INDICATOR LIGHT IS TOO BRIGHT MAKING IT DIFFICULT TOO SEE AT NIGHT. *JB
