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 beacon, you must have a good understanding of automotive electrical
procedures and systems, along with proficiency in the installation and use of safety warning
equipment.
• When drilling into a vehicle structure, ensure that both sides of the surface are clear of anything that
could be damaged.
• Locate the light control so the VEHICLE and CONTROL can be operated safely under all driving
conditions.
• Do not attempt to activate or deactivate the light control while driving in a hazardous situation.
• Frequently inspect the light to ensure that it is operating properly and that it is securely attached to
the vehicle.
• 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 that the
driver can maintain safe vehicle operation.
• 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 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.
• File these instructions in a safe place and refer to them when maintaining and/or reinstalling the
product.
