Quick Steps on Changing the Headlight Adjusting Screws
The headlight adjusting screw allows you to easily change the aim of your car's headlights, so if they break you won't be able to adjust the headlight beam. Luckily, replacing broken headlight adjusting screws is quite easy and only takes around 30 minutes or so including readjusting the headlight.
Difficulty level: Easy
- Tape measure
Step 1: With your car parked directly in front of a wall or a closed garage door, pop open the hood and look for the screws. The position of the headlight adjusting screws varies from the make and model of the vehicle, though they are usually found on the top of the headlight assembly.
Step 2: Using the screwdriver, turn each screw counterclockwise to loosen them from the headlight assembly. Note this will also change the aim of the headlights.
Step 3: Screw in the new adjustment screws.
Step 4: Once the replacement headlight adjusting screws are in place, you now have to re-aim your headlights. Place a strip of tape horizontally on the wall or door in front of each headlight parallel to its height. Next, Place a vertical strip of tape in front of the vertical center of the headlight assemblies. This will give you two targets to use to re-aim the headlights.
Step 5: Measure 25 feet away from the wall and mark the spot with a piece of tape. Reverse your vehicle until the headlights line up with the tape on the ground.
Step 6: Turn on the headlights. Turn the adjustment screws to adjust the horizontal and vertical aim of the headlight beams. Ideally, the high intensity beam should hit the wall two inches below and to the right of the center of the tape target. This is so that the beams can fully illuminate the road and street signs ahead.
