I got a 6000k 35w HID kit. They look nice and I like them so far, for now, as long as they are working lol. I have yet to see or hear of a good brand, and they always seem to be hit or miss and very unpredictable. The first 8k hid kit I tried didn't even turn on and fire the bulbs up. Ive tried cheap ones, expensive ones , not so expensive ones, all pretty much seem to be the same Japanese crap all rebranded with different labels. Usually people get the kits for dirt cheap and sell them for a huge profit.
If you do try an hid kit, I would just get the cheapest one you can buy on eBay or something, that way when they burn out your not as mad and didn't waste as much money, maybe pick up a second kit for spare bulbs ballasts. 55w hid kits are brighter, but generate a lot more heat than the 35 Wat kits which are still very bright..though less likely to cause the damage as Scott described..still doesn't mean things can't happen, but I haven't really heard of anyone having melting problems with 35 watt ...
if you don't need them for the greater light output, just mainly for looks/color to match the led drls, just get the Hoen halogen fog bulbs and skip the headache and aggravation.
