Here is how you can aim your headlights. On a level ground shine the lights against a flat even surface. The head light to the surface distance is 25 feet. Measure the center of the head light on the vehicle and measure the height on the wall in the center of the beam. You can now adjust the center of the beam 1 in. below the height of the vehicle light height. You can eyeball the left to right adjustment, and be very close...................That's I how its done!
