I'm having problems installing my light tooI don't have any illustrations, but I can kinda guide you...
You will need a pretty wide phillips screwdriver. Look on top of the headlight. There are two gaps in between the headlight and the plastic, and in each one of those, there are white plastic slots that fit a phillips driver. Those are what adjust the headlight.
Just take it on a flat road, with like a large lid, and do each headlight one at a time. Forget that whole crazyniess of against a white wall, etc. Just find a good beam spot, and line them up.
If you need more help, PM me and I can call you and walk you through it.
