PERMANENT MOUNT INSTALLATION INSTRUCTIONS
IMPORTANT: Please read all of the following instructions before installing your new light.
1. CAUTION: All of our DC powered warning lights are polarity sensitive. These lights are
polarity protected only if the appropriate fuse is used. All wires connected to the
positive terminal of the battery should be fused at the battery for their rated load.
Testing the light before this fuse is properly installed will void the warranty
on the light.
2. Your new warning light comes complete with a foam mounting gasket, mounting
screws, lock washers, and well nuts.
3. For any models utilizing a flange mount base, please skip to Step 6.
4. This light come equipped with a combination base, allowing
the light to be either mounted on a 1/2" NPT conduit pipe or
permanently mounted. For NPT pipe, mount the light using
the threaded entrance hole in the base of the light, then skip
to Step 11. For the permanent mount, proceed to Step 5.
5. Carefully remove either the four screws near the base of
the lens and lift off the lens. Examine the inside of the base
and use a punch or drill to remove the knockouts present.
6. Next, you will need to drill the holes in your mounting surface. Place the gasket in the
exact position the light is to be mounted, and mark the holes on the mounting surface.
(NOTE: You might have to stretch the gasket slightly to find the location of the holes in
the gasket.) Take care to ensure that the gasket does not move while you are marking
each of the holes. Be sure to mark the center hole if you will be running your wires
through the mounting surface.
7. Remove the gasket and drill your holes
using an appropriate 3/8" drill bit.
CAUTION: If you are mounting the
light on a vehicle, and plan to wire it
through the roof of the vehicle,
remove the headliner from the inside
of the vehicle. If you do not remove
the headliner, take care so that you
do not drill through it.
