Step-by-step Adjustment Process
Properly adjusted headlights help you see the road clearly. They also make sure other drivers can see you. Follow these simple steps to adjust your car headlights.
You will need a flat wall, a tape measure, and a screwdriver. Make sure your car is on a level surface and the tires are properly inflated.
Marking The Wall
Park your car about 25 feet from a flat wall. The wall should be clean and smooth for clear marks. Turn on your headlights in low beam mode.
Use tape to mark the wall where the headlights hit. Mark the center of each light beam. Also, mark the horizontal and vertical center of your car’s headlights on the wall.
- Measure the height from the ground to the center of each headlight.
- Transfer this height to the wall and place a horizontal tape line.
- Mark the center points of the headlights on the wall with vertical tape lines.
Adjusting Vertical Aim
Locate the vertical adjustment screws on your headlights. These screws move the beam up or down. Use a screwdriver to turn the screws slowly.
Adjust until the top of the headlight beam aligns with the horizontal tape line on the wall. This ensures the light is not too high and won’t blind other drivers.
- Turn the screw clockwise to raise the beam.
- Turn the screw counterclockwise to lower the beam.
- Check both headlights to keep them at the same height.
Adjusting Horizontal Aim
Find the horizontal adjustment screws. These screws move the beam left or right. Turn the screws carefully to change the beam’s direction.
Adjust so the center of each beam lines up with the vertical tape marks on the wall. This keeps your headlights pointing straight ahead and not to the sides.
- Turn the screw to move the beam toward the car’s centerline.
- Turn the screw the opposite way to move the beam outward.
- Make sure both beams are aimed evenly.
Testing Headlight Alignment
Checking your headlights helps ensure you see clearly at night. Proper alignment prevents blinding other drivers.
Testing headlight alignment lets you know if adjustments are needed. It is a simple and important safety check.
Nighttime Check
Testing headlights at night shows how well they light the road. Find a dark, flat area for this test.
Turn on your low beams and park about 25 feet from a wall or garage door. Look at the light beams and their height.
- The beams should be even and aimed slightly down.
- They should not shine too high or too far to the side.
- If beams are uneven or too bright, adjust your headlights.
On-road Testing
Drive on a quiet, dark road to test how your headlights perform. Check for clear visibility and no glare.
Notice if the lights illuminate the road well and if you can see signs and obstacles in time. Ask a friend to watch if your lights blind oncoming traffic.
- Make sure the road ahead is well lit.
- Check if the lights cover both sides of the road.
- Adjust if the lights cause glare or do not light the road enough.
