Xenon HID replacement bulb (4300k vs 6000k)

[Toneaero]

Does anybody know the size of the stock OEM HID bulb? Its for a 2010 x5M. Im assuming its the same bulb for all E70 platform. I haven't been getting a clear answer via google....it might be D1S bulb?

What I want to do is replace the yellowish 4300k stock bulbs with something on the lines of 6000k.

Has anybody done this?

Not knowing your exact build date, upon looking at realoem.com for a 2010 X5M it is a D1 bulb.

Thanks for the awesome link. My build date is 09/09. Anyways, that confirms my findings of using a D1 bulb.

Does anyone know if the stock headlight housing is a (S) shield or a (R) reflector housing? The aftermarket bulb im finding is a D1S bulb...for a shield type headlight housing. Does it even matter?

D1S bulb is a D1S bulb. Going for 6K?

Yes, I had 6k to even 6500k HIDs on other cars before and I like the white with a very slight hint in blue.

After a bit more research, bulbs with an "R" usually have a painted section that diverts the light pattern. Bulbs with an "S" are for housings like the X5 where its a projector beam housing. This bulb has no paint on it.

Watch for another thread in the near future with HID kelvin swap!
