If you can't align headlights with proper equipment, use this method. Park the car 10ft from a dark wall or board. Draw a vertical line on the wall in line with the car's center. Bounce the car to settle suspension, then measure the height from the ground to the headlights' center. Draw a horizontal line on the wall at this height. Mark a cross on this line on either side of the vertical line, representing the distance between the light unit and car center. Remove headlight rims and switch to full beam. Adjust the screws on each light to align the beam centers with the crosses. Bounce the car again to check alignment and dipswitch operation. Replace the headlight rims. This is a temporary fix until proper adjustment can be done.

Test the replacement bulb to ensure it functions correctly by activating the switch to illuminate the bulb. Close the bulb access panel and the vehicle's hood.
