i adjusted my Zenons a few weeks ago & it was realy easy. All I did was turn the up/down screws half a turn anticlockwise (out) & that lifted the beam up quite a lot. You should not need any more than that, infact a quater of a turn would have probably been enough. You have to lie with your back on the engine to see what you are doing (on an old blankeet or something) with the lights turned OFF as there are a few thousnd volts in the light circiut, then shut the bonnet & see how it went. I had the lights shining on the garage door when it was getting dark to see where they shone to. Just do one at a time to get a comparison. Let me know how it goes
