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 at least 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 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.
• Halogen light bulbs and strobe tubes are pressurized and, if
broken, can burst and result in flying glass. Always wear gloves
and eye protection when handling these components.
• 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.
