The LED color and the lens color must match. Either use a clear lens or
match the color of the lens with the LED. Using a lens colored differently

than the LED color will greatly reduce the light output and reduce the ef-
fectiveness of the light for emergency signaling purposes.
Failure to follow this warning may result in personal injury or death to you
or others.
SET ONLY ONE CONTROLLER
When putting together systems of VIPER EXT light heads, ensure there is
only one controller light head. If more than one light head in a system is a
controller, the follower light heads will malfunction.

ROOF SUPPORT STRUCTURE
There is a roof support member that spans the distance between the driver’s
and passenger’s side. DO NOT DRILL THROUGH THIS MEMBER! Ad-
just any hole locations until the holes can be drilled without going through
this support.
Failure to follow this warning will weaken the roof of the vehicle and may
lead to an increased chance of bodily injury or death in a roll over accident.
LOCATING OPERATOR CONTROLS
Locate the light system controls so the VEHICLE and CONTROLS can be
operates safely under all driving conditions.
Failure to heed this warning could result in driver distraction or driver er-
ror while operating the vehicle.

AIRBAG DEPLOYMENT
Do not install equipment or route wiring in the deployment path of an
airbag.
Failure to observe this warning will reduce the effectiveness of the air bag, or
potentially dislodge the equipment, causing serious injury to you or others.
DRIVER VISION
Do not install the light in a location that will obstruct or impair the driver’s
vision. Always locate the light out of direct view of the driver and test the
system to make sure excessive stray light from this light does not impair the
driver’s vision. Make sure you minimize both direct light and reflected light
from the driver’s vision.
Failure to follow this warning could result in injury or death.
DRILLING PRECAUTIONS
Before drilling holes, check the area into which you plan to drill to ensure
you do not damage vehicle components while drilling. All drilled holes
should be deburred and all sharp edges should be smoothed. All wires going
through drilled holes should be protected by a grommet or convolute/split-
loom tubing.

Wiring the VIPER EXT in the Vehicle
WIRING PRECAUTION
Never attach both the orange wire AND the yellow wire from the CON-
TROLLER light head to the same FOLLOWER light head. Connecting
both signal wires to the same FOLLOWER will cause the light heads to
malfunction.
REVERSE POLARITY / MISWIRING
Reverse polarity or incorrect voltage may damage the light. To avoid dam-
age to the light, ensure that the battery voltage is the same as the voltage
rating of the light and that the correct polarity is observed. If you are con-
necting to a cigarette lighter plug, connect the positive wire to the center
terminal and connect the negative wire to the outer terminal.

Cleaning the Light Heads
CRAZING/CHEMICALS
Crazed, cracked or faded domes or reflectors reduce the light output and
the effectiveness of the lighting system. Domes or lenses showing this type
of aging must be replaced.
Failure to follow this warning may result in bodily injury or death to you
or others.
USE PROPER CLEANING AGENTS
Do not use cleaning agents that cause crazing such as strong detergents, sol-
vents, or petroleum products. If crazing of lenses does occur, reliability of
the light for emergency signaling may be reduced until lenses are replaced
