I AM FINDING THAT THE NEWER VEHICLES WITH THE LED TAIL LIGHTS ARE VERY DISTRACTING. WHEN FOLLOWING THESE CARS AND MOVING MY EYES FROM SIDE TO SIDE THE PWM SWITCHING FREQUENCY CAUSES ME TO SEE A STROBING EFFECT. THIS SEEMS TO BE WORSE ON THE CADILLAC'S WITH THE LARGER TAIL LIGHTS. BUT THERE ARE GETTING TO BE MORE AND MORE CARS WITH THE NEW LED LIGHT. APPARENTLY WHEN THE BRAKES ARE APPLIED THE LIGHTS GO ON STEADY AND I DO NOT SEE THE EFFECT. SOME OF THE NEWER SIGNS ON SOME OF THE KWIK TRIP STORES IN OUR AREA ARE ALSO DISTRACTING. WHEN SEEN IT MAKES ME THINK THERE IS A FIRE TRUCK OR POLICE CAR WITH THE FLASHERS ON. IT WILL BE A BIG PROBLEM WHEN MORE CAR COMPANIES START USING THEM. *TR
