Question about daylight bulb
 

i searched on ebay with saying "2006 x5 daylight bulb" and nothing comes out. is theres other name? i want to change the yellow looking daylight bulb to something else

What about changing daylight to headlight?

You mean the Day Running Lights I assume.
Those are the ordinary halogen bulbs,unless you have a xenon(I still don't know what bi-xenon setup means since I have a xenon only for low beams)
And yes,halogen lights are yellow.

my low beams are xenon and daylight are yellow. i would like to turn off the daylight or buy nicer color. which one should i do?

It just using regular halogen High Beam bulbs (9006 i think.) you can buy a blue tint bulbs
it will light up a little whiter, or heading to your indy shop they can turn it off for you with their GT1 computer.

i see, thank you i should goto the shop this light is useless to me

Not to change topic but i got a ques too, I have bi-xenon so the halogens are not used at all (I do not have DRL enabled) can it be used as regular lights with the xenons or is it for DRL only, just seems like a waste.

In Xenon lights there is a piece of metal next to low beam xenon bulb (inside the projector) which makes the correct pattern to avoid blinding other drivers. In Bi-Xenon lights this piece of metal is movable and when you switch to high beams it moves away so that it doesn't cut the light from the middle anymore. So effectively same bulb is acting as both low and high beam (hence "bi"). In addition to that there is also the halogen bulb next to xenon which here in EU is used as an additional high beam and lights up together with Bi-Xenon high beam mode. That gives pretty good high beam light level at dark.

Btw. I already ordered xenon swap kit to replace my halogen high beam with 50w xenon. That way I would have "double xenon" high beam setup which should be really bright. But here in north it's pretty dark during the winter so it comes handy :D.
