Ford Mustang Owners Manual: Adjusting the headlamps

The headlamps on your vehicle are properly aimed at the assembly plant.

(4) Horizontal reference line

2. Measure the height from the center of your headlamp to the ground and mark an 8 ft (2.4 m) horizontal reference line on the vertical wall or screen at this height (a piece of masking tape works well). The center of the lamp is marked by a 3 millimeter circle on the headlamp lens.

3. Turn on the low beam headlamps to illuminate the wall or screen and open the hood. To see a clearer light pattern for adjusting, block the light from one headlamp while adjusting the other.

On the wall or screen, you will observe a flat zone of high intensity light located at the top of the right hand portion of the beam pattern.

If the top edge of the high intensity light zone is not at the horizontal reference line, the headlamp will need to be adjusted.
