Thanks, but that thread is no different than telling me to use a wrench and adjust the screws on the back of the headlights.
What I am looking for is more specific information. I tried adjusting the screws, clockwise and counter clockwise but I do not see any difference. The only thing different is the little level on the top of the headlight changes, but the beam on the wall does not change. I remember on my NX, there was a screw with a white end to play with and that made a difference on the height of the beam.
