safety functions or circuits. Always check the vehicle for
proper operation after installation.
• The lighting system components, especially the outer
housing, get hot during operation. Be sure to 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.
• Do not attempt to wash any unsealed electrical device while
it is connected to its power source.
• DO NOT connect this system to the vehicle battery until
ALL other electrical connections are made, mounting of
all components is complete, and you have verified that no
shorts exist. If the wiring is shorted to the vehicle body or
frame, high current conductors can cause hazardous sparks,
resulting in electrical fires or flying molten metal.
• DO NOT install equipment or route wiring (or the plug-in
cord) in the deployment path of an airbag.
• Before drilling into a vehicle structure, ensure that both sides
of the surface are clear of anything that could be damaged.
Remove all burrs from drilled holes. To prevent electrical
shorts, grommet all drilled holes through which wiring
passes. Also, ensure that the mounting screws do not cause
electrical or mechanical damage to the vehicle.
• Because vehicle roof construction and driving conditions
vary, do not drive a vehicle with a magnetically mounted
warning light installed. The light could fly off the vehicle,
causing injury or damage. Repair of damage incurred
