Safety Message to Installers and Service Personnel of Warning Lights
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 servicing of safety warning equipment. Always
refer to the vehicle’s service manuals when performing equipment installations on
a vehicle.
Light Hazards
• In order 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 maintain safe vehicle operation.
• 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. Verify or test your combination to make sure 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.
