The lenses on mine are fine. I replaced the housings a few years ago They were 13 years old or more. The reflectors are considered the worst ever made. I agree with that assessment. What i'm buying should be as good or better than stock LED lights on new trucks. I don't plan on selling my truck anytime in the next few years.
I do plan on ceramic coating the lenses on the new ones so they have the best chance of lasting a long time.
