Hi. Some suggestions from experience with rally cars.
25 feet from vertical wall, on levle ground, weight inside equal to driver, normal load, fuel, and so forth.
Adjust low beams straignt out and level. Find marks on wall by pulling up, putting mark or tape at center line of headlamp on wall. A laser pointer works great! Back up 25 feet or so.
Adjust horizontally straignt ahead.
Adjust vertically so 'hot spot' (brightest spot) is 3 inches lower than tape. Drive & check. Big thing is straight ahead. Eurobeam lamps with good
edge make it easer to find center on wall.
Driving lights should be straight ahead both horizontally and vertically, then adjusted per personal desires.
Remember to weight the vehicle - including what you might normally carry in the rear. If the lights change angle when you load up, you'll need to adjust vertical aim. Keep the correct tool handy because things will probably change in the boonies, carrying lots of stuff, so on.
