There are two manual adjusting knobs on each headlight unit, one on the far (closest to the front quarter panel and one towards the middle. They are adjustable by a 6mm allen or by hand (hand is quite hard though). Be real careful when adjusting them as it is easy to get them too high, or uneven! I have played with both and it adjusts the high and low beams, hope that helps!rkaufman said:Is there any way to manually level my bi-xenons? I've done a search but have been unsuccessful in finding anything. Thanks.
The knobs you are talking about are the same ones. At the center of those knobs is a hole that accomodates a 6mm allen!sfzBimmer2 said:On my 2002, there are large adjustment knobs on the Xenon assembly. Did they replace those with the allen wrench knobs, or do these serve a different purpose?
