I love the halo rings, aka 'angel eyes', but am not fond of the yellowish color. I know that it's an H8 bulb, which is not very common and has to be ordered. The only difficulty is that the xenon matched bulbs are blue in color and I know have an output less than that of a regular halogen bulb.

Has anyone had success in switching to a xenon colored bulb? How is the light output (brightness)?

On my e46 M3, I've got real HIDs in place of my fog light bulbs. While I thought about it for the X5, I think they're too high to put HIDs in them, for fear of blinding oncoming cars since it's not a projector lens. I also toyed with the idea of using HIDs for the halo rings/DRLs, but will need to find somewhere to place the ballast. There is not much room back there, and I would probably have to run the ballast outside of the housing, which would mean a hole through the housing.

Or am I just crazy?
