You can search the internet and find out the "general" procedure to aim headlights. Overall, not difficult as long as you have a flat, level surface and a white wall.
The problem is that there seems to be a variety of distances to set the correct aim. Some say 16 feet from the "screen", others 25 feet, another 32 (10 meters).
I set mine this evening at 16 feet. Drove the car, and no one flashed at me, so maybe I'm good. The real test will be on the drive to Ohio.
Thanks,
