Note:

Before you start adjusting the Light, be sure to first check the alignment of your Lights. Park the vehicle about 10 to 25 feet from the wall with the headLights directed at the wall. HeadLight center lines must not be higher than 3.5 feet above the ground.​

1. Find the adjustment screws. First, put the adjusting bolts in your vehicle.

2. Adjust the headLights individually. The headLights must be adjusted one at a time. Lay a rag or towel on a chair facing the Light you want to block. Covering the Light assembly directly may damage the plastic lens.

3. Adjust the vertical field. Turn the screw at the top of the Light housing clockwise to raise the Lights and counterclockwise to lower the Light. The headLight should be adjusted until the top of the brightest part of the Light beam shines directly on or just below the center of the tape line on the wall.

4. Adjust the horizontal field. The screw on the side of the Light housing needs to be turned to get the correct right/left adjustment. Adjust the lens so that the strongest part of the beam is to the right of the vertical line.

5. Test your results.
