I need to aim my headlight before I drive my car tonight. The car is a 73 Roadrunner. Does anybody have a way of doing it at home ? any tips or tricks on what to aim them at ?

Park the car about 30 feet from the garage door and aim the lights on it.

I just turn the headlights on at night against the garage door with the car 10-15 feet away. Of course you need to have a fairly level driveway.

The spec in the old service manuals is:
25' from a wall, mark the wall with headlamp height and where straight ahead is.
Adjust low beams to that height, and a few inches to the right of straight ahead. Same deal with high beams if separate (4-headlamp cars).

on a level surface, driveway works... walk about 15 paces, tape a line on a wall or grage door about 3" hight turn lights on and adjust you want the drivers side a tad to the right not "spotlighting" on coming traffic

Thanks guys I got it done
