Lights The dome light will only go on when the dome light switch is in the delay or ON position. HEADLAMP 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 3.0 mm circle on the headlamp lens. 3. Turn on the low beam headlamps to illuminate the wall or screen and open the hood. 4. On the wall or screen you will observe a light pattern with flat edges at the top of the beam pattern. If the flat edges are not at the horizontal reference line, the beam will need to be adjusted. To see a clearer light pattern for adjusting, you may want to block the light from one headlamp while adjusting the other. 5. Locate the vertical adjuster on each headlamp, then use a 6 mm Allen wrench or screwdriver to adjust the headlamp up or down. 6. HORIZONTAL AIM IS NOT REQUIRED FOR THIS VEHICLE AND IS NON-ADJUSTABLE. 7. Close the hood and turn off the lamps. 29 2005 Thunderbird (tbr) Owners Guide (post-2002-fmt) USA (fus)
