1. Physical Mounting
2. Strobe Head installation
Mount the power supply in a clean, dry location. Mounting the
unit to a flat metal surface will aid in heat dissipation. Use the
power supply as a template to mark the hole locations. The
mounting holes will accept up to a 1/4" bolt.
Plug the strobe light heads into the outlets. Keep the following in
mind:
• Heads connected to outlets 1, 3, 5 flash at the same time.
Note: The power
supply baseplate must be connected to chassis ground (GND) to
reduce radio interference.
• Heads connected to outlets 2, 4, 6 flash at the same time.
• Heads connected to 1, 3, 5 alternate with heads 2, 4, 6.
The
divides equally between all strobe heads
installed. Example: 90 Watts into 2 heads = 45 Watts per head.
Consider this before selecting the number and type of strobe
heads to install. Do not exceed the wattage rating of the head.
If you have purchased a pre wired switch harness, follow the
included instructions. If you are wiring the system yourself
follow the instructions below and the diagrams on the next page.
• Connect the RED wire to battery positive (+) or a fuse panel
circuit rated for at least 15 AMPS.
• Connect the BLACK wire to battery negative (-) or directly to
vehicle chassis.
• The VIOLET wire controls HIGH / LOW power. Low power
limits the flash intensity for nighttime use. Connect VIOLET to
+12/24V for LOW, leave VIOLET disconnected for HIGH.

Note: Use the correct size wire for power connections.
The length of the wires determines the size needed.
1 to 7 ft. use 18AWG wire.
7 to 14 ft. use 16AWG wire.
14 to 25 ft. use 14AWG wire.
25 to 35 ft. use 12AWG wire.
Note: VIOLET, YELLOW, GREEN, BLUE, WHITE, and ORANGE are all
circuits and can be wired with a minimum of 22AWG wire.
