SAFETY MESSAGE TO INSTALLERS AND USERS
People’s lives depend on your safe instal-
lation of our products. It is important to
read, understand and follow all instruc-
tions shipped with the products. In addi-
tion, listed below are some other impor-
tant safety instructions and precautions
you should follow:
• To properly install a light assembly:
you must have a good understanding
of automotive electrical procedures
and systems, along with proficiency
in the installation and use of safety
warning equipment.
• DO NOT install equipment or route
wiring in the deployment path of an
air bag.
• When drilling into a vehicle struc-
ture, be sure that both sides of the
surface are clear of anything that
could be damaged.
• A light system is a high current de-
vice. In order for it to function prop-
erly, a separate ground connection
must be made. It should be connected
to the negative battery terminal.
• Locate light system controls so the
VEHICLE and CONTROLS can be
operated safely under all driving con-
ditions.
• You should frequently inspect the
light to ensure that it is operating
properly and that it is securely at-
tached to the vehicle.
• File these instructions in a safe place
and refer to them when maintaining
and/or reinstalling the product.
Failure to follow all safety precautions and
instructions may result in property damage,
serious injury, or death to you or others.

system. This strobe head can be powered
by several types of strobe power sup-
plies. Consult local codes and regula-

all the components. Before performing any installa-
tion, plan all wiring and wire routing.
