Safety Message to Installers 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.
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 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. Combining
light heads and a power supply from different manufacturers may reduce the warning effectiveness of
the lighting system and may damage the components. You should verify or test your combination to
ensure that the system works together and meets federal, state, and local standards or guidelines.
Electrical Hazards
• A light system is a high current system. In order for the system to function properly, a separate
negative (-) connection and positive ( +) connection must be made. All negative connections should
be connected 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.
• The lighting system components, especially light bulbs, strobe tubes, LEDs, and the outer housing,
get hot during operation. Disconnect power to the system and allow the system to cool down before
handling any components of the system.
• Do not mount a radio antenna within 18 inches (45.7 cm) of the lighting system. Placing the antenna
too close to the lighting system could cause the lighting system to malfunction or be damaged by
strong radio fields. Mounting the antenna too close to the lighting system may also cause the radio
noise emitted from the lighting system to interfere with the reception of the radio transmitter and
reduce radio reception.
