I realize that there are about nine million posts about this on here, and I have read Zulus explanation a few times, but I seem to be confused on exactly how all this comes together specifically for my car.

I have a 2005 X5. It has the angel eyes, etc. I just bought it and after a couple days of owning it I quickly realized I have Halogens and not Xenons. This was kind of surprising to me cause even though it's a 3.0i, I have sport pack, premium pack, cold weather, bluetooth, and navi. All I want is the regular head lights to be Bi Xenon HID.

Anyways what I could really use help on is a shopping list of what I would need to start. I would like to use OEM parts anywhere possible and have a good local connection at BMW to get the parts at a reasonable price.

Is there one part number for the ballast, bellow, bulb assembly shown in zulu95's tutorial?

Can I install the bulb into my exist socket and projector housing where the halogen bulb is? Or do I need to get a whole different head light housing to make this happen correctly?

What is the electrical setup. I see the Ballast needs grounded and has a couple other connections maybe?

Do I need a new wire harness or adapter for the extra current draw?

Do I need these relays? Can I buy them somewhere? How / what do they connect to?


That should be a good start. Any information would be helpful. I feel like a lot of the threads on here are relative to prefacelift and / or people who want full kits / after market mods.

Thanks for all the help in advance. I have found Xoutpost is extremely helpful already in installing some after market audio, bluetooth info, and navi update info.
