If your headlights don't seem properly aimed or you've installed new headlights, you may want to adjust the alignment of the beams for optimum night visibility.
- Choose a location on level ground in front of a blank wall or a garage door. Position the vehicle so it's perpendicular to the wall and about 25 feet back.
- Set up a double-crossbar target on the wall, using black electrical tape (figure A). Measure the distance from the center of one headlamp to the center of the other. Use this as the span between uprights of the crossbars. Now measure the distance from the ground to the horizontal midline of the headlight. Let this be the height of the horizontal bar.
- With the vehicle 25 feet from the wall and the headlights on low beam and aimed at the crossbars, adjust the vertical and horizontal alignment screws on each headlight until each beam is centered exactly (figure B). You may need to raise the hood to get to the adjustment screws.
- Note: This method will give you an approximate adjustment. To have your headlights aligned precisely, take your car to an auto-service center.
