I WOULD LIKE TO COMPLAIN ABOUT THE NEW HEADLIGHTS ON THE LATEST MODEL CARS, THEY MAY BE NICE FOR THE DRIVER OF THE AUTO BUT, THE GLARE AND NON-DIMMING TO THE ONCOMING DRIVER, I FEEL IS A DEFINITE HAZARD TO THE ONCOMING DRIVER. I AM ALSO CONCERNED ABOUT THE "FOG LIGHTS" THAT MANY CARS HAVE, IF THEY WERE TRULY FOG LIGHTS THEY WOULD BE YELLOW. WE DON'T NEED 4 HEAD LIGHTS. PLEASE GIVE SOME SERIOUS THOUGHT TO THESE CONCERNS. THANKING YOU IN ADVANCE. *JB
