I already knew this had been done before. One of my customers is a car dealer that deals in alot of Audis, and he has a few perfectly good Audi HID projectors laying around, scratch and dent kinda stuff that I could get really cheap. I had been tossing the idea around in my head, Like Curtis says though, getting alignment perfect is going to be difficult. I had a set of the drop in HID bulbs in H4 housings in my zuk, and while they were great on the trail, on the road people were constantly flashing their high beams at me. Without the projector lens focusing the light downward the ebay HIDs just spread the light out too much.
