Sorry about bring this back... I have read very much everything at forum about headlight aiming, including one from Daniel Stern http://www.danielsternlighting.com/nhtsa/NHTSA.html

Unfortunately w/ all these reading, I still dont get a sense of a good way aiming the HID, w/o going back to dealer. Has anyone at the forum able to achieve this?

BTW, my x5 is 2001. xeon right side - i think its ok (was aiming toward right for some weird reason) xeon left - low. right highbeam - ok. left highbeam -ok
