WHILE DRIVING ON I-95 AT NIGHT, WITH ONCOMING TRAFFIC, LEGALLY FORBIDDING THE USE OF HI-BEAMS, A DEER, I BELIEVE, SUDDENLY CROSSED THE ROAD, 50-75 FEET IN FRONT OF MY VEHICLE. THE LOW BEAMS ON THE VEHICLE ARE SO POOR I WAS UNABLE TO SEE THE DEER UNTIL IT WAS DIRECTLY IN FRONT OF THE VEHICLE. I HAD TO SLAM ON THE BRAKES AND VIOLENTLY SWERVE TO THE RIGHT, LEAVING THE ROAD SURFACE IN A SIDEWAYS SLIDE, CROSSING THE SHOULDER AND FINALLY STOPPING ON THE GRASS, HEADING DOWN HILL, ONLY INCHES FROM A POST. THIS LACK OF EFFICIENT HEAD LIGHTING, NOW KNOWN TO BE FROM HEADLIGHT UNIT SEAL FAILURE LEADING TO LOW LIGHT LEVELS FROM THE PROJECTORS, CAUSED THIS ACCIDENT. THE PASSENGER STRUCK HER HEAD ON THE PASSENGER WINDOW AND SUFFERED A BUMP AND BRUISE TO THE RIGHT SIDE OF HER HEAD. IT IS NOW MY UNDERSTANDING THAT MITIGATING THIS SEAL FAILURE WILL COST ME ABOUT $1600.00 AT THE CADILLAC DEALER. ADDITIONALLY, I UNDERSTAND THAT THE ONLY REPLACEMENT AVAILABLE FROM CADILLAC IS THE SAME UNIT THAT HAS FAILURES AND THAT NO UPGRADED UNIT HAS BEEN MADE. ADDITIONALLY, I UNDERSTAND THAT CADILLAC HAS BEEN FOUND LIABLE IN A CLASS ACTION SUIT REGARDING THESE FAULTY HEADLIGHTS IN FLORIDA AND CALIFORNIA, HOWEVER, NOT IN MY STATE OF RESIDENCE, ALTHOUGH, COINCIDENTALLY, MY ACCIDENT OCCURRED IN FLORIDA. THESE 300,000 VEHICLES NEED TO BE INVESTIGATED FROM MODEL YEARS 2010 TO 2016, AS THEY ALL USE THE SAME HALOGEN HEADLIGHTS. IT IS ONLY A MATTER OF TIME, UNLESS ALREADY OCCURRED, UNTIL LOSS OF LIFE IS SUFFERED F
