1. Open the hood of your Celica.
2. Locate the black plastic headlight bezel.
3. There will be two screws attached to the headlight bezel. The top screw is the vertical adjustment screw.
4. Use a Phillips-head screwdriver to turn the screw clockwise or counterclockwise to adjust the vertical aim of the headlights.
Horizontal Adjustment Screw:
1. If you need to adjust the horizontal aim of your headlights, you can do so by turning the hexagonal screwdriver adjustment bolts located to the left of the headlight assembly bracket.
2. Turn the screws with a 6 mm (0.24 in) hex screwdriver to adjust the headlight to the left or right.
