1. First, install the Strobe Power Supply in a protected loca­tion using the power supply itself as a template. THE POWER
SUPPLY MUST BE MOUNTED TO A METAL SURFACE.
Make sure all connectors are easily accessible.

2. Install the strobe light heads in the preferred locations.

3. String the 3 conductor cables between the lights and the
power supply . Make sure the cable is secure along the cho­sen routing inside the vehicle to prevent it from damage by
chafing or binding. Be sure to keep the cable away from en­gine hot spots.

WARNING

Strobe tube cables with 500V insulation resistance
must be used. Automotive cable is not suitable and
should not be used.

NOTE

When routing the cable, make sure the end with the
closed tip terminals (male pins) is toward the power
supply and the end with the open tip terminals (female
pins) is toward the light head.

4. Insert the pins on each end of the cables into the connec­tors. Each end of these cables has a factory crimped pin on
each of the three wires, see Figure A.

the strobe lights to be switched into low power or reduced
intensity . This feature is useful for night time use. When the
grey(brown) wire is powered, the power supply is switched to
low intensity . When the power is removed, the power supply
switches to high intensity mode. Use 18 gauge wire to ex­tend the flash control wires to a customer supplied switch as
shown in Figures B, C and D.

8. Connect the red wire to the positive (+) side of the battery
making sure to place a customer supplied 15 Amp fuse at the
battery . Connect the black wire to the negative (-) side of the
battery or to the vehicle chassis.

NOTE

T o extend the power (+) and ground (-) wires, use the
following as a guide.

1 to 10 ft. use 16 AWG wire
10 to 20 ft. use 14 AWG wire
20 to 30 ft. use 12 AWG wire
30 to 50 ft. use 10 AWG wire

Figures B, C and D show some of the standard switch control
options that can be easily wired to complete a Strobe Light
System.

Figure B shows a high/off control system that quad flashes
all heads.

Figure C shows a high/low control system that quad flashes
all heads.

Insert wires with female pins into
the proper locations in the female
WP connector:

NOTE

It is important to follow the correct color code when
inserting the pins into the connectors.

5. Connect the cables to the strobe light heads.

6. Next, plug the other end of the cable into the Light Head
Output Socket on the Strobe Power Supply.

7. Using Figure E, select a flash pattern and determine which
flash control wires will need to be used. The grey(brown) wire
controls the day/night (high/low) intensity feature of the power
supply, see Figure C. The high/low intensity feature allows

Figure D shows how any flash option could be installed de­pending on which flash control wire(s) are attached to the
switch.
