Place the light on the roof of vehicle and determine a point on the roof where the light will be level in all directions Use light base to mark three mounting holes and a grommet hole on roof, using a sharp point tool Drill three 9/64" diameter mounting holes and one 1/2" diameter grommet hole in roof. Place furnished grommet into 1/2" diameter hole and run electrical wire through grommet, sliding the wire between the roof and the upholstery toward windshield or side. Attach end of wire to the dash switch and connect remaining terminal on dash switch to any lead which comes directly from the "hot" side of the battery. A 25 amp switch is required for installation. To prevent leakage, the grommet and wire should sealed with a mastic compound on the roof opening.

The rubber washers provide a leak proof seal plus space the lamp above the roof so that the retaining band can be removed and replaced with no difficulty.
