Here's a general outline of the process, but consult your owner's manual for precise instructions and diagrams relevant to your vehicle's trim level and headlight setup. The owner's manual will show you the exact location of the adjustment screws and any specific procedures needed.
General Steps (May Vary):
1. Safety First: Park on a level surface, away from traffic, and turn off the engine. Engage the parking brake.
2. Locate Adjustment Screws: You'll need to find the adjustment screws on the back of each headlight assembly. These are usually accessed by removing parts of the headlight assembly itself (potentially the entire headlight unit for some trim levels). They're often small and may require a small Phillips head screwdriver or similar tool.
3. Identify Adjustment Directions: Each screw typically controls either vertical (up/down) or horizontal (left/right) adjustment. There will be a screw for vertical aim (up and down) and horizontal aim (side to side) for each headlight.
4. Prepare for Adjustment: You'll need a flat, vertical surface (like a wall) at least 25 feet away. Measure the height of your headlights from the ground. Mark this height on the wall. Park your car so the headlights are aimed at the wall. Turn on your headlights (low beams).
5. Make Adjustments: By turning the adjustment screws, you can move the light beam's position on the wall. Generally:
* Turning the screw clockwise will typically raise (vertical) or move the beam to the right (horizontal).
* Turning the screw counter-clockwise will typically lower (vertical) or move the beam to the left (horizontal).
6. Check and Fine-Tune: After each adjustment, check the beam's position on the wall. Repeat the adjustment process until the beams are properly aimed. The goal is to have both headlights aimed at the same height and centered. You want the aiming point to be slightly below the horizontal center line.
7. Reassemble: Once you've achieved the correct aim, carefully reassemble any parts you removed to access the adjustment screws.
8. Final Check: Drive your car on a road and check your headlights' illumination pattern to make sure they are properly aligned and don't blind oncoming drivers.
Important Considerations:
* Headlight Assembly Removal: Accessing the adjustment screws might involve significant disassembly, including removing the grille, bumper fascia, or even the entire headlight assembly. Again, consult your owner's manual for specific instructions.
* Professional Help: If you're unsure about any of these steps, consider taking your Roadmaster to a qualified mechanic or auto repair shop for headlight adjustment. Improper adjustment can be dangerous.
* Bulb Condition: Ensure your headlight bulbs are correctly installed and in good working condition. A damaged bulb can affect the beam pattern.
Remember to always prioritize safety. If you are not comfortable performing this task yourself, seeking professional assistance is recommended.
