Solution

1. Preparation

Gather tools: Flathead screwdriver or Torx bit (specific to the Mustang model), tape measure, and a level surface.
Safety warning: Ensure the vehicle is parked safely with the engine off and the headlights turned off before starting.

2. Access the Headlight Adjustment Screws

Open the hood of the vehicle.
Locate the headlight assembly; the adjustment screws are usually located on the top or side of the assembly.
Identify the horizontal and vertical adjustment screws (refer to the owner’s manual for specific locations).

3. Adjust Headlight Alignment

Vertical Adjustment:
- Using the flathead screwdriver or Torx bit, turn the vertical adjustment screw to raise or lower the headlight beam.
- Clockwise typically raises the beam, while counterclockwise lowers it.
Horizontal Adjustment:
- Turn the horizontal adjustment screw to move the beam left or right.
- Clockwise usually moves the beam to the right, while counterclockwise moves it to the left.

4. Verify Alignment

After making adjustments, recheck the height and alignment of the headlight beams against the marked lines on the wall.
Make further adjustments if necessary until the beams are properly aligned.
