Kinda old too, but here...
Well, I got tired of the glare and scatter from my HID Plus SPW 4800K high/low HID kit, so I decided to do something a little different. I purchased a set of BMW Bi-Xenon HID's off of Ebay for $335 shipped from Finland! It came complete with brand new bi-xenon projectors, ballast, bulbs, and wiring harnesses.
I decided to paint the projector housing black, because I wasn't too fond of the silver metal finish. I also obtained a second set of headlight housings. Anyways, I baked the headlight housings and popped them open. I took out the reflective housing, and dremeled the back away, so that the projector could fit in behind. I decided to mount the projector to the reflector so I can still utilize the stock aiming points of the headlight. Here are some pictures of the projector mounted to the back of the reflector. (The reflector housing is VERY thick, so there are no worries of it cracking from the weight of the projector.)
After that I put back the lights together and sealed and siliconed it up. As far as wiring, it was extremely easy, as you just tap off the wiring harness. there are only 4 wires, power and ground for low beams, and power and ground for high beams. So with that all wired up, it was time to light them up and aim them! Initial aiming was way off, one side was really low and the other really high. But after correctly aiming them, they are really nice!! Here are some pictures of them lit up.

Overall, I am EXTREMELY happy with them. The cutoff line is amazing, and the high beam feature is even better. These lights light up the road very evenly, with no scatter or "hot spots." For $335, I am way more impressed than my $420 SPW kit. The only downside was that it took me 2 COMPLETE days to do this installation, but I can tell you, it was worth EVERY minute!
btw. They are 4100k HID's, not no 6000k mumbo jumbo.
