I ordered a set of them with the upgraded ballast (non-slim) a few days ago, and I got it yesterday. Installed it this morning. It's hard to find a spot to ground the ballast in the bumper, so I ended up making my own ground wire to attach to body. Anyway, the HID kits are bright, but it does take a while to warm up, much slower compared to my stock even with the upgraded ballast. The other thing is, every once in a while, I get a left fog light dash error in my car. It comes and goes. I wonder if my unit is defective or something... Anyway, I've only had it for the day, so we'll see how it goes...
I just noticed that my left and right fog light reflectors reflect different patterns...I wonder why.
