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. In addition, listed below
are some other important safety instructions and precautions you should follow:
Before Installation or Service
Qualifications
• To properly install or service this equipment, you must have a good understanding of automotive
mechanical and electrical procedures and systems, along with proficiency in the installation and
service of safety warning equipment. Always refer to the vehicle’s service manuals when performing
equipment installations on a vehicle.
Light Hazards
• To be an effective 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.
• Do not install the light system in an area that would block, impair or blind the driver’s vision. Ensure
that the light system is mounted in a position that is outside of the driver’s field of vision, so the driver
can safely operate the vehicle.
• Federal Signal power supplies and light heads are designed to work together as a system. Com-
bining light heads and a power supply from different manufacturers may reduce the warning ef-
fectiveness of the lighting system and may damage the components. You should verify or test your
combination to ensure the system works together and meets federal, state and local standards or
guidelines.
Electrical Hazards
• Strobe systems present a shock hazard because they use high voltage to operate. Do not handle
strobe cables, the power supply or bulbs or remove the lens while the equipment is connected.
Strobe systems can also hold their charge even after they have been turned off. After disconnecting
power to the unit, wait five minutes before handling any parts of the strobe system.
• A light system is a high current system. For the system to function properly, a separate negative
(–) connection and positive (+) connection must be made. All negative connections should be con-
nected to the negative battery terminal and a suitable fuse should be installed on the positive battery
terminal connection as close to the battery as possible. Ensure that all wires and fuses are rated
correctly to handle the device and system amperage requirements.
• 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
affect vehicle operation or mandated safety functions or circuits. Always check the vehicle for proper
operation after installation.
