This is how I adjust mine. On a level surface, drive car up to a wall or garage door and stop about 2 feet from surface. Turn lights on and mark an 'X' with tape where center of beam is. Back up about 20 feet and see where center of beam is now located. Lift hood and if you look at headlight assembly, you should see up/down and side to side adjustment screws. Just adjust lights so that center of beam is just a bit lower the 'X' and centered side to side on 'X'.
