Had a bit of a front end knock which managed to break the bolt lugs on my headlights, so I'm in the process of fitting a new pair. I've put one on and it seems to be aiming too high. I know you need a proper beam aligner to set up alignment correctly, but is there a rough way of setting up alignement. i.e if you park a certain distance from a wall, how far up should the centre of the beam pattern be? Any advice appreciated. Cheers Simon
