How to Set Automotive Lights for Night Driving

1). Open the hood of your vehicle and locate the headlight adjustment screws. These screws should be depicted in your owner's manual are often marked with "+" and "-" symbols. They're usually just behind the headlight assembly.
2). Park your vehicle a foot or two away from a garage door or wall and on level ground. Do this in the evening when it's dark enough to see the headlight beams.
3). Place a horizontal strip of masking tape along the wall at the height of the center of your headlight lenses.
4). Place two small vertical strips across the horizontal tape to mark the distance between the center of each headlight lens.
5). Measure 20 feet from the wall and back the car straight from the wall to place the front bumper at the 20-foot mark.
6). Turn on your headlights at the low-beam setting. Open the hood and use a Phillips head screwdriver to adjust the vertical and horizontal aim of each beam so the brightest part of the beam strikes the wall 4 inches below and to the outside of each center mark on the wall.
