Installation & Mounting
1. Mark off and drill four ¼” diameter mounting holes and the 1” wire hole on the vehicles mounting surface using
the dimensions shown for the appropriate light (refer to Figures 4, 5 & 6). Verify free clearance exists behind the
mounting surface for wires and fasteners before drilling.
2. Install customer supplied grommet in the 1” diameter wire hole. Install the four plastic grommets in the mount-
ing holes (Code 3 supplied).
3. Route the vehicle power wires and allow a minimum of 3” of slack to protrude from the center opening at each
light head location. Use 18 AWG for wires up to 40’ length, 16 AWG for wires up to 70’ length.
4. Refer to the section “Device Operation” prior to finalizing the electrical connections. Prepare the vehicle
power wires and the light heads wires with terminations of the customer’s choice (not supplied) as follows: Red:
+12 VDC, Black: Ground, White: Program, Purple: Dim, Yellow: Sync, Green: Cutoff (refer to Figure 1). Water
-
proof connectors are recommended.
5. Route the power wires through the center opening of the light gasket or bezel and bezel gasket (refer to
Figures 2 and 3). Connect light head red (+12VDC) power wires and Black ground wires to the vehicle power
system.
Seal or cap the end of the white wire and other unused wires to prevent inadvertent changes to
the flash pattern or unexpected operation of the device.
6. Verify proper light head operation by supplying electrical power to the system wires.
7. Push the assembled electrical connectors through the center opening and into the vehicle.
8. Install the lens gasket over the light head.
9. Place the light head onto the light gasket or bezel and bezel gasket. The bezel and all gaskets are marked
with the word “Top”. The light head is not, but should be installed such that the wire harness is located directly
across from the hole in the vehicle body.
10. Install onto the light head the outer lens and secure to the vehicle using the four supplied #6 x 1 ¼” screws.
