Default Re: Focus Headlight Adjustment not working

I went for a drive and the distance of the light throw was greatly improved and much better lighting of the road.
I then tried High Beam (separate reflector with H1 bulb) and the high beam lights were shining up into the trees! Obviously the point of aim of both low and high have gone up when I adjusted the low beam (the high beam was previously aimed correctly) - so obviously there is something wrong with the low beam reflector or bulb mounting. Any ideas?
Remember the first time you tried adjusting and nothing was happening? Maybe you were turning the high beam adjustment and didn't know it. Just a guess, I dont know focus.
With the low beams, the usual thing to do when you run out of adjustment in one direction, is to loosen the bolts that hold the whole headlight assembly, move it in the desired direction then retighten to lock it in place. The idea is to move it a bit too far in the required direction so then you can wind back the adjuster.
