I replaced my chevy's headlights to LED bulbs, I found a blog from AUXITO on how to orientations. They recommend 25 feet away from wall. Center of tire to wall. Before and after would have been awesome. the top of the hot spot should be at the same height as the lamp center at 25ft. I adjusted the up/down after install. If the headlight assembly is to high or up it won't be bright on the road but appear to be brights to on coming drivers. If it's too low or down it won't output far. You have to find that in between.
