Adjustment
After the XT308AS light is securely installed, loosen the adjusting screws located on each end and tilt the light to the desired
angle. Then tighten the screws. Turn the XT3xx LED light on and check the light from the front or rear of the vehicle, through
the window, to ensure that it is at the most desirable angle, and that the light is not impeded by any obstacles and/or window
tinting.
Troubleshooting
The XT308AS have been factory tested and approved. If the light fails to work, check the following:
1. Press the Function Switch (User Supplied) to be sure the “Off” pattern is not selected.
2. Remove the fuse from the vehicle fuse box and check to see if it has blown.
