i just purchase a 2001 530i, and it has a halogen headlight and angel eyes, i wanted to changed it over to xenons, and was wondering if there was a way to change the color of the angel eyes (the halogen color) to like a white or blue to match the xenon headlights when i purchase some. I noticed that there is a bulb for the angel eyes but it appears to be attached to a casing that attaches directly to the headlight assembly, and the bulb doesn't seem to come of the casing.... any help??
