Correct Method For Aiming Headlights?

No kidding. I considered becoming Calif. certified in headlamp adjustments and brake adjusting (the two main credentials for okaying junk yard rebuilts!), and I sent away for the free state manuals. The headlamp adjusting manual is 77 pages!!!

Gnarly.

Measure the center of your headlight to the ground. Park on a flat, smooth surface, facing a wall, parked exactly 25 feet away. Make 2 marks on the wall inline with your car, at the same height as your headlamp centerline, and draw a horizontal line the width of your car, on the wall, connecting these points.

Set a deep socket on the exact center of your hood, close to the grille. Place another one in the exact center of your trunk. Stand behind the car, and look through the windows so that you can line up both sockets. Mark the wall where that line would hit it. Make this line go from the ground to 4 feet above the ground.

Measure the distance from the socket on your hood to the center of each headlamp, and go to the wall, and make coresponding marks, relative to the existing lines on the wall. You should end up with a pair of crosses on the wall that are roughly in the same place as your headlamps are.

Turn on your low beams. You want each one to sit so it's upper most part of the beam is below the horizontal lines in the crosses, and so that it is two inches to the right of the crosses vertical lines.

Take care,
