Review on KC HiLiTES 7" Round 60/55w H4 DOT Headlight - Set of 2: Perfect Lighting Solution by Jonathan Suarez

I've been using these headlights for a little over four years. A few days ago my first lightbulb burned out in them. When I went to change the lightbulb, I noticed that the rubber boots had weather cracks. I called KC to buy new ones, assuming it was long out of warranty. They said no, not only sold the boots but filed a warranty claim against them. Ten minutes after submitting a claim on their website they replied and said replacement boots would be delivered tomorrow - great customer service. And their warranty is twenty-three (23) years. When a bulb burned out, the remaining bulb emitted more light than the two original factory headlights combined. It should also be noted that one of the reasons I bought these headlights is because they are made out of Lexan. I'm towing my jeep behind an RV that likes to throw rocks at the headlights. I've been driving the jeep for four years now and the rocks haven't bothered it at all - great light.
