Here's the low down on aiming your headlights. Low beams do not aim straight ahead when aligned. They point down and to the right. This keeps from
blinding oncoming drivers.
High Beams are not named High because of an increased candlepower; they are named High because the beam is aimed higher. High beams aim straight, out
from the headlight when the low beams are correctly adjusted. That's the reason you can be blinded by High beams from oncoming traffic.
Try this solution:
Flat wall (I use my garage door!)
1. Park about 25 feed from the wall on the level!
2. Measure the height of the headlights, at their center.
3. Measure the height of the light beam at its center.
4. Adjust the LOW beam so the center of the beam is about 2" below center of the headlight height.
5. If you have done the adjustment correctly the High Beam should follow, it's locked in.
If you make a two-inch error at 25 feet, the error compounds with distance. It becomes an error of about two feet, 300 feet distant. 300 feet is a point at
which you should be able to view a person.
Repeat steps 1 - 4, only, measure the separation between the headlight centers. The separation of beams, center to center, on the wall should be the same as the headlights.
5. Move the Low Beam about 2 inches to the right.
I think this will get you in the ballpark.
