The ProComp lights are excellent. I have the 135W stainless ones on my YJ. I used to have KC's and hated them. The KC's come with something like a 24 year warranty but if you live anywhere near the ocean like myself, then you'll be taking them in every year for replacements because of rust. I didn't have the stainless KC's but still, you'd think that for the price you pay for KC's, they'd last a little longer....I've even had non-stainless cheap brands that lasted longer than the KC's.
