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.

The headlights in early models are replaceable sealed-beam units containing both high-beam and low-beam filaments; if one filament fails, the entire unit must be replaced. To replace the headlight unit, first remove the screws holding the decorative trim ring, taking care not to disturb the headlight adjusting screws. For rectangular headlight units, remove the four retaining ring screws, while for round units, loosen the retaining ring screws and rotate the ring counterclockwise to release it. Pull the headlight unit out enough to access the rear and disconnect the plug. Replace it with a new unit of the same size and type, ensuring proper alignment with the bucket. Install the retaining ring and trim ring if applicable. For halogen bulb headlights, ensure the headlamp switch is off, lift the hood, and locate the bulb at the rear of the headlamp body. Remove the bulb retaining ring by rotating it counterclockwise, then carefully pull the bulb straight out and unplug it from the electrical connector. Insert the new bulb without touching the glass, aligning the grooves in the base with the tabs in the socket, and secure it with the retaining ring. After installation, check for proper operation, noting that a properly aimed headlamp typically does not need re-aiming after bulb replacement. For headlight assembly replacement, remove the parking/turn/side indicator light assembly by unscrewing the upper screws and lower nuts, unplug the bulb connectors, and completely remove the assembly. Then, unsnap the upper headlight assembly retainers, turn the horizontal adjuster out of the adjusting nut, and remove the headlight assembly from the vehicle, reversing the process for installation. Proper adjustment of the headlight is necessary after installation.

To replace sealed beam headlights, first disconnect the negative battery cable from the battery. Remove the headlight bezel screws and take off the bezel. Next, remove the headlight retaining screws without disturbing the adjustment screws, then take out the retainer and pull the headlight out enough to disconnect the electrical connector before removing the headlight completely. For installation, plug in the electrical connector, position the headlight, and secure it with the retainer and screws. Finally, place the headlight bezel back and install the retaining screws, ensuring to have the headlights adjusted by a dealer service department or service station as soon as possible. For halogen bulb types, open the hood and disconnect the electrical connector from the back of the bulb. Rotate the retaining ring about 1/8-turn counterclockwise and slide it off the base, then carefully pull the bulb straight out of the socket. Insert the new bulb into the socket, ensuring the flat on the plastic base is upward, align the socket locating tabs with the grooves, and push the socket firmly into the base. Slide the retaining ring on and turn it clockwise until it stops, then plug in the electrical connector, test the headlight operation, and close the hood. Adjust the headlights at a dealer service department or service station at the earliest opportunity.

If adjusted incorrectly, they could blind the driver of an oncoming vehicle and cause a serious accident or seriously reduce your ability to see the road.

Pull the parking/turn/side indicator light assembly from the grill opening and unplug the bulb connectors. Remove the assembly completely.

If the headlights are adjusted incorrectly, they could blind the driver of an oncoming vehicle and cause a serious accident or seriously reduce your ability to see the road.

The simplest method requires a blank wall 25 feet in front of the vehicle and a level floor.

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.
