Hi, we have a 2009 E70 X5, im trying to change the factory HID bulb to 6000k, but i cant find any DIY, and i cant seems to get behind the housing to change the bulb, do i need to take out the headlight housing to do so just like my A4? and i noticed the X5 has bi xenon, im not sure is it the correct terms, the high beam are coming from the same projector, do i need special bulb or something? i found the bulb type is D1S according to sylvania, anything i need to be aware of? thanks in advance.
