Wow, quite the involved procedure but he does have some interesting products.
I'm with Tim, I park on a level surface about 15-20' from a wall/door and get the beams about level and slightly inside the fender lines. Then I go to a level road in the area and see where they hit, obviously, at night and fine tune from there.
I've used the tool that sits on the bulb from my service station era and I can tell you from experience that they weren't all that accurate either. They were sort of a good starting point and we still tweaked from there.
Does anyone have a headlight alignment tool? Or, does anyone have a good ‘field’ alignment method.
Pretty detailed account of how to do it here
