Headlight recommendation

I second keeping the headlights waxed. I usually hit mine with wax when I wax the whole truck (1-2 times a year). Sometimes I'll hit them with Meguair's Ultimate compound if they start looking a little dull.

My experience with the eBay headlights is they are coated with a crappy film that tends to peel after enough UV exposure. I put lenses from DEPO headlights on mine because some other members said they don't have the cheap coating and don't haze.
