Just to share some experience....
Currently mine is E60 facelift using H8 bulbs for angel eyes.
Didn't like the yellowish stock color; wanted to change to white or blue....
Red may not be legal in Singapore??
Tried Autobacs, only had white bulbs (no brand), cost ard 20 bucks. Color is ok but dimmer. So used them for my fog lights which turned out ok.
Had searched the net b4; found on ebay a slight bluish white bulb (luminics). However, color is still dimmer, but better than the local ones. So used them on my angel eyes. For some reason the intensity of the stock bulbs are higher, even tho all of them are the same at 35 W.
Hopefully someone can come up with something better. LED will be great!
