WIRING AND TABLE INFORMATION:
OVER-VOLTAGE PROTECTION
When an over-voltage condition is detected, the module will flash
an overvoltage warning pattern of 50mS ON/950mS OFF to alert
of the overvoltage condition and protect the electronics from
damage due to heat/voltage.
THERMAL COMPENSATION PROTECTION
The LED module is designed to provide maximum power output
while providing protection to the electronic components by re-
ducing the output power at extreme temperatures.
Lights are chassis-grounded. If you need to
ground-switch the light, you must isolate the lights
metal backing, heatsink, studs and/or screws from
the body of the vehicle or use a relay.

Connecting the Green wire to ground before applying power to
the Red or Orange wires will place the LED module into remote
mode and the light output color will be directly controlled by the
input wires as shown below. For Cruise mode or Low Power con-
trol of the LED module, the signal to the control wires must be 100

WIRING AND TABLE INFORMATION (CONT.):
SIMULTANEOUS/ALTERNATE
This function can only be changed when the LED module is
in a flashing mode (disabled in cruise or steady ON functions)
and only has an effect when at least 2 LED modules have the
green sync wire connected together. When the light is flash-
ing, momentarily connect the white wire to ground for >3S
and <4S (light will go steady high, steady low, off, steady high)
then release. The light module will switch between Simulta-
neous and Alternate each time this sequence is done. To have
light modules flash simultaneously, both light modules need
to be set to the same sequence type (Set-Up Table). To have
light modules flash alternately, the light modules need to be
set to different sequence types (Set-Up Table).
ADVANCE PATTERN
Flash pattern can only be changed when the LED module is in
a flashing mode (disabled in cruise or steady ON functions).
When the light is flashing, momentarily connect the white
wire to ground for >250mS and <1S (light will go steady high)
then release. The flash pattern will advance to the next pat-
tern. If the light module was at the last pattern, the pattern
will reset to the 1st pattern.
BACKUP PATTERN
This function is only valid when the LED module is in a flash-
ing mode (disabled in cruise or steady ON functions). When
the light is flashing, momentarily connect the white wire to
ground for >1S and <2S (light will go steady high, steady low)
then release. The flash pattern will backup to the previous
pattern. If the light module was at the first pattern, the pattern
will change to the last pattern on the list.
PATTERN RESET
This function is only valid when the LED module is in a flash-
ing mode (disabled in cruise or steady ON functions). When
the light is flashing, momentarily connect the white wire to
ground for >5S and <6S (light will go steady high, steady low,
off, steady high, steady low, off) then release. The flash pat-
tern will reset to the 1st pattern in the list.
FACTORY RESET
This function is only valid when the LED module is in a flash-
ing mode (disabled in cruise or steady ON functions). When
the light is flashing, momentarily connect the white wire to
ground for >6S and <7S (light will go steady high, steady low,
off, steady high, steady low, off, steady high) then release.
The LED module will reset to: pattern=1, Function Table=1,
Color Swap=OFF, Simultaneous.
LOCKOUT CONFIGURATION WIRE
This function will disable the wire tap configuration mode
that is activated by holding the white wire to ground. The
lock out is activated by applying ground to the white wire for
>7 seconds and <8 seconds per the table below. The function
can be disabled by tapping the wire to ground and releasing
8 times within 5 seconds. The light will flash 8 times when the
feature is enabled or disabled to notify the user of a setting
change.
BACKUP HIGH/LOW POWER
To be compliant with government regulations, a Backup Light
System consisting of Dual Backup Lights shall be operated in
Low Power. A system consisting of one Single Backup Light
shall be operated in High Power.

If held longer than 8 seconds, the light will go back to flashing
the current pattern and no action will be taken.
SYNC 2
Synchronizing flashing of multiple light modules is accomplished by
connecting the Green wires of different light modules together. Up to
24 light modules can be connected for synchronized flashing. All light
module flash patterns must be set to the same flash pattern # to ensure
proper operation. Refer to Sequence Type section in the Setup Table to
setup light modules to flash in alternate or simultaneous flash pattern.
NOTE: Will NOT work with non-Sync 2 products, such as Ghost, LED3,
and 4 wire Intersector. WILL WORK with Sync 2 products nFORCE Sec-
ondary Lights, nFORCE FIT, and 5 wire Intersector Lights.
