MOUNTING INSTRUCTIONS - SPOTLIGHT
Magnetic Mount Shoe
(Models 7901GT, 7951GT, 79014GT and 79514GT)
1. Select the best location for mounting the magnetic shoe. Make
sure the metal area under the magnetic shoe is flat and clean to
ensure a strong bond.
2. Aluminum vehicles will require a magnetic base adapter kit (p/n
16308). Visit our web store at http://store.golight.com
Permanent Mount Shoe
(Models 7900GT and 79004GT)
1. Determine the location for the light on your vehicle. This should
be a flat surface. The small arrow on the base indicates the
normal forward direction of the light. The light will rotate to
the left of this arrow 185 degrees and to the right 185 degrees.
The lamp will tilt down 45 degrees and tilt up 90 degrees. The
location should take into consideration this range of motion to
maximize usability. Keep in mind the swing diameter is 261.4
mm (10.3 inches) from the center of the permanent mount
shoe – see Figure 1. This allows for clearance as the light is
rotating.
2. The permanent mount shoe is designed to be mounted with
either sheet metal screws or a combination of cap screws, nuts
and washers. You should choose hardware appropriate to the
surface to which you intend to attach the light. Drill holes in
mounting surface for either type of hardware depending upon
your preference. Refer to Figure 1 for hole pattern dimensions.
3. Place the black mounting gasket under the mounting shoe and
attach the shoe and gasket to vehicle using preferred hard-
ware. Silicone or other like sealants should not be used around
the mounting gasket as it will limit the ability to drain water
properly.

reprogramming the remote to the spotlight to prevent cross-talk
with other spotlights in your fleet or in your area. Reprogramming
simply involves changing the DIP switch settings inside the remote
