Lights Vertical aim adjustment 1. Park the vehicle directly in front of a wall or screen on a level surface, approximately 25 feet (7.6 meters) away. • (1) 8 feet (2.4 meters) • (2) Center height of lamp to ground • (3) 25 feet (7.6 meters) • (4) Horizontal reference line 2. Measure the height from the center of your headlamp to the ground and mark an 8 foot (2.4 meter) 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 mm 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. For vehicles with halogen headlamps: 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. For vehicles with HID headlamps: There is a distinct cut-off (change from light to dark) in the left portion of the beam pattern. The top edge of this cut-off should be positioned two inches (50.8 mm) below the horizontal reference line. 60 2012 05+ Mustang (197) Owners Guide, 3rd Printing USA (fus)
