the accepted method is to use a headlight alignment tool or device wich is
a purpose built tool. in Pa. it's a required tool for all state inspection
stations and is "supposed to be" part of a "real" state inspection. (like
that ever gets checked any more!)
most mechanics have turned headlights on so many times in a shop checking
"function" that they are aware of where each beam falls against the shop in
front of them and only "wild" variations call out for adjustments.
i do headlight adjustments on a dark country level road . stand in front
of 1 headlight so i can see where 1 beam is going at a time and "dial 'em
in". but i have done a lot of headlight adjustments over the years as a
state inspection mechanic.
the end result has the right headlight going down the edge of the road
(straight forward)and the left headlight just starting to shine inwards of
the centerline of the road towards the center line of the car(now this is a
left hand drive kinda guide line! not a right hand drive country advice!).
this keeps the left headlight out of oncoming driver's eyes and puts most
of the focused combined light in front of you. it's not very easy if you
have not done a few ! it might be easier to go to your local garage with
the headlight trim off and ask them to "focus" or "adjust" them for you?
you still need to figure out how far out front low beam is going to
effectivly shine and once you hit high beam if you are lighting the highway
or spotting trees for roosting birds at night!
