I was driving home late last night on an unfamiliar road and really do need them sorting. Following another car was fine but when they turned off I could see nothing. Do you really need a beam setter to adjust them then? I've just had my MOT and the guy got something the size of a big cctv camera on a mount with a convex glass lens on the front and put it at the front of the light. Is that a beam setter? How much would I be looking at to set them up properly?
To do it right you need a beam setter. Otherwise you may go too high and blind people coming the other way. That's the sort of thing that you described before. It's literally 5 minutes work. If it was me I'd prob do that for nothing/pint. Depends how nice your local garages are. Any MOT place can do it.
