Safety Message to Installers and Service Personnel of Warning Light Equipment
People’s lives depend on your proper installation and servicing of Federal Signal products. It is important to
read and follow all instructions shipped with this product and the original product. Listed below are some
other important safety instructions and precautions you should follow.
• To properly install this light, you must have a good understanding of automotive electrical procedures
and systems, along with proficiency in the installation and use of safety warning equipment.
• Always refer to the vehicle’s service manuals when performing equipment installations on a vehicle.
• Never attempt to install aftermarket equipment that connects to the vehicle wiring without reviewing
a vehicle wiring diagram available from the vehicle manufacturer. Ensure that your installation will not
aect vehicle operation or mandated safety functions or circuits. Always check the vehicle for proper
operation after installation.
• When drilling into a vehicle structure, ensure that both sides of the surface are clear of anything that
could be damaged.
• In order for the light to function properly, a separate ground connection must be made. If practical, it
should be connected to the fusible link at the front fender between the negative (–) battery terminal
and chassis ground. At a minimum, it may be attached to a solid metal body or chassis part that will
provide an eective ground path as long as the light system is to be used.
• Locate the light control so the VEHICLE and CONTROL can be operated safely under all driving
conditions.
• If a seat is temporarily removed, verify with the vehicle manufacturer if the seat needs to be
recalibrated for proper airbag deployment.
• Do not attempt to activate or deactivate the light control while driving in a hazardous situation.
• This product contains high intensity LED devices. To prevent permanent eye damage, DO NOT stare
into the light beam at close range.
• Frequently inspect the light system to ensure that it is operating properly and that it is securely
attached to the vehicle.
• Do not install equipment or route wiring in the deployment path of an airbag. Failure to observe this
warning will reduce the eectiveness of the airbag or potentially dislodge the equipment, causing
serious injury to you or others.
• File these instructions in a safe place and refer to them when maintaining and/or reinstalling the
product.
Failure to follow all safety precautions and instructions may result in property damage, serious injury, or
death to you or others.

Overview
The Federal Signal Viper SignalMaster is a directional light assembly for use in a flashing mode. The
lens colors available are amber (standard) and red.
The Viper SignalMaster provides two distinctive directional signals: left arrow and right arrow. In
addition, an alternating flash pattern produces a warning signal for use when a directional signal may
not be appropriate. When a directional signal is selected, the lamps are individually illuminated in a
sequential sweeping motion until all eight lamps are illuminated. The brake module, which operates
independently from the control module, is located at the center of the light bar.
These lights are for secondary warning only. They are not for use as a primary warning
system. Failure to use these lights as intended may cause property damage, personal injury,
or death.

Installing the Viper SignalMaster Light Assembly
STATIC SENSITIVE DEVICE: The circuitry can be damaged or destroyed by electrostatic
discharge (ESD). To prevent ESD, observe anti-static procedures during installation.
Install the light assembly as described in the instructions included with the mounting kit. Route the
cables to the planned location of the control unit.
Installing the Control Unit and Completing the Wiring
UNIT REQUIRES VENTILATION: The control unit needs to radiate heat. Do not install it in an
area where it cannot dissipate heat into the air. Do not mount the unit near a heater duct or
under the hood.
NOTE: Plan all wiring and cable routing before selecting a mounting location for the control unit.
1. Install the control unit and complete the wiring as described in the instructions included with the
control unit.
REVERSE POLARITY/MISWIRNG: Reverse polarity or incorrect voltage may damage the light.
To avoid damage 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.

3. Slide the faceplate into the extrusion. Ensure that the faceplate is captured by the tabs of the
extrusion.
4. Reconnect the cable assemblies.
5. Replace the end cap.

Testing the System
LIGHT HAZARD: To be an eective warning device, this product produces bright light that can
be hazardous to your eyesight when viewed at a close range. Do not stare directly into this
lighting product at a close range, or permanent damage to your eyesight may occur.
SOUND HAZARD: All eective sirens and horns produce loud sounds (120 dB) that may cause
permanent hearing loss. Always minimize your exposure to siren sound and wear hearing
protection. Do not sound the siren indoors or in enclosed areas where you and others will be
exposed to the sound.
After the installation, test the emergency warning system to ensure that it is operating properly.
Also test all vehicle functions, including horn operation, vehicle safety functions, and vehicle lighting
systems to ensure proper operation. Ensure that the installation has not aected the vehicle operation
or changed any vehicle safety functions or circuits. After testing is complete, provide a copy of these
instructions to the instructional sta and all operating personnel.
Cleaning the Plastic Lenses
CRAZING/CLEANING SOLUTIONS: Cleaning solutions, such as strong detergents, solvents,
and petroleum products, can cause crazing (cracking) of the light bar lens and reectors. To
clean the reectors, use a soft, damp cloth. To clean the lens, use a soft cloth and a solution of
water and a mild detergent.
CRAZING/CHEMICALS: Crazed, cracked or faded lenses or reectors reduce the light output
and the eectiveness of the lighting system. A lens or reectors showing this type of aging
must be replaced. Failure to follow this warning may result in bodily injury or death.
1. Rinse the lenses with lukewarm water to loosen dirt and debris.
2. Use a mild soap, lukewarm water, and a soft cloth to gently clean the lenses. To avoid damaging the
lens, do not use heavy pressure or caustic, abrasive, or petroleum-based cleaners.
3. Rinse and dry the lenses with a soft cloth to prevent water spotting.
4. To remove fine scratches and haze, use a specialty plastic cleaner/polish and a soft cloth. You can
also use a high quality automotive paste cleaner/wax that is non-abrasive.
