Tools needed:
- Phillips head screwdriver
- Masking tape
- Measuring tape
- A level surface and a wall
Step 1: Prepare your Jeep and the adjusting area
Park your Jeep Wrangler JK on a level surface, approximately 25 feet away from a wall. Ensure the vehicle is perpendicular to the wall and that the headlights are turned off. Use masking tape to create a horizontal line on the wall at the height of your Jeep's headlights.
Step 2: Locate the headlight adjustment screws
Open your Jeep's hood and locate the adjustment screws on the back of each headlight assembly. There should be two screws, one for vertical adjustment and one for horizontal adjustment. The vertical adjustment screw is usually marked with an "up and down" arrow, while the horizontal adjustment screw is marked with a "left and right" arrow.Step 3: Adjust the vertical alignment
Turn on your Jeep's headlights and stand in front of the vehicle. Using a Phillips head screwdriver, turn the vertical adjustment screw clockwise to lower the beam or counterclockwise to raise it. The center of the low beam should be slightly below the horizontal tape line on the wall.Step 4: Adjust the horizontal alignment
For horizontal adjustment, turn the corresponding screw clockwise to move the beam to the right or counterclockwise to move it to the left. The headlights should be centered on the vertical axis and not pointing towards oncoming traffic.Step 5: Fine-tune and test
Once you've completed the initial adjustments, take your Jeep for a test drive on a dark road to ensure the headlights are properly aligned and providing optimal visibility without blinding other drivers. If necessary, make additional fine adjustments using the same process.It's important to note that headlight alignment specifications may vary depending on the year and model of your Jeep Wrangler JK. Always consult your owner's manual for specific instructions and specifications before making any adjustments.
By following these steps, you can easily adjust your Jeep Wrangler JK's headlights, ensuring optimal visibility and safety for you and other road users.
