headlight adjustment
With old DOT style headlights this was relatively easy. I dunno if Xenons can be adjusted correctly without proper headlight adjusting equipment. Either type is adjusted using a reflector type measuring device. The tricky part for Xenons is the self levelling operates from signals on the suspension delivering vehicle attitude signals to an ECU which adjusts headlight height. While I believe there would still be a manual alignment, certainly for left to right aim, the height might be controlled by software and be practically non adjustable. Headlight adjustment normally involves two screw adjusters accessible from the back of the light housing, if it can be done at all. The top screw adjusts height and the side screw adjusts left/right aim.
Xenons are so bright it can be very dangerous to have them set too high,(or incorrectly left to right) for you as well as for oncoming so be careful adjusting outside factory spec. This is why adjustment must be automatic, and also why headlight washers are mandatory and must not be disabled.
