Solution

1. Preparation

Gather necessary tools and equipment.
Ensure the vehicle is on level ground.
Have the car's headlights turned on.

2. Locate Adjustment Screws

Open the hood of the vehicle.
Locate the headlight adjustment screws. Typically, there are two screws per headlight: one for vertical adjustment and one for horizontal adjustment.

3. Adjust Vertical Alignment

Use a Phillips screwdriver or a suitable tool to turn the vertical adjustment screw.
Turn the screw clockwise to raise the beam and counterclockwise to lower it.
Adjust until the top of the beam is level with the tape mark on the wall.

4. Adjust Horizontal Alignment

Use the horizontal adjustment screw in a similar manner.
Turn the screw clockwise to move the beam to the right and counterclockwise to move it to the left.
Adjust until the center of the beam is aligned with the vertical tape mark.

5. Final Check

After adjustments, turn off the headlights and close the hood.
Repeat the alignment check to ensure the adjustments are correct.
