I have a 2000 M5 and am wondering what my options are with regards to the fog lights. The headlights are obviously the nice, white HID lights but the fog lights are the standard yellow lights. I believe the fog lights us the standard 9006 bulbs. Has anyone replaced them with, say, the PIAA ultra white bulbs or even some Hella (or other brand) 9006 HID conversion kit with ballast?
Thanks.
