tion of our products. It is important to read,
understand and follow all instructions
shipped with the products. In addition, listed
below are some other important safety
instructions and precautions you should
follow:
• To properly install this light: you must
have a good understanding of automotive
electrical procedures and systems, along
with proficiency in the installation and
use of safety warning e uipment.
• This product contains high intensity LED
devices. To prevent permanent eye
damage, DO NOT stare into the light
beam at close range.
• DO NOT install e uipment or route
wiring in the deployment path of an air
bag.
• When drilling into a vehicle structure, be
sure that both sides of the surface are
clear of anything that could be damaged.
• In order for the light to function prop-
erly, a separate ground connection must
be made. If practical, it should be con-
nected to the negative battery terminal.
At a minimum, it may be attached to a
solid metal body or chassis part that will
provide an effective ground path as long
as the light system is to be used.
• Locate light control so the VEHICLE and
CONTROL can be operated safely under
all driving conditions.
• Do not attempt to activate or deactivate
light control while driving in a hazardous
situation.
• You should fre uently inspect the light to
ensure that it is operating properly and
that it is securely attached 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.
A. GENERAL.
The Model GL5 is a flush mount LED light designed to
be used in a flashing mode. Lens colors (amber, red, or blue)
are specified when ordering.
B. INSTALLATION.
NOTE
or maximum coverage and effectiveness, the light
assembly should be mounted in a horizontal
orientation in pairs: one in front and one to the
side.
1. Determine the desired mounting location. Using
the flange, scribe drill position marks on the mounting
surface for the 4mm mounting bolts. A 5-7/16" x 3-11/16"
rectangular hole is required for clearance. Center the
rectangular hole between the mounting holes.
CAUTION
Before drilling or cutting holes in ANY part of the
vehicle, be sure that both sides of the mounting
surface are clear of parts that could be damaged;
such as brake lines, fuel lines, electrical wiring or
other vital parts.
2. Drill four mounting holes in the mounting surface.
Cut the clearance hole.
3. Secure the light assembly to the mounting surface
using the supplied hardware as shown in figure 1.
C. ELECTRICAL.
NOTE
The light is completely wired at the factory and
does not require additional internal wiring. All the
conductors necessary for control of all functions are
contained in the cable.
The basic light function of the unit must be controlled
by a user supplied flasher. Before proceeding, ensure that
the light assembly has been installed on the vehicle in
accordance with the instructions.
WARNING
Light system controls must be located so that
the VEHICLE and CONTROLS can be oper-
ated safely under all driving conditions.

Figure 1.
1. Route the user-supplied control cable into the
vehicle near the eventual location of the user-supplied
flasher.
WARNING
To prevent personal injury and/or damage to
vehicle components, in the event of a short
circuit in the power cable, install a fuse in
each incoming cable conductor.
2. or proper light operation, the light assembly
control cables must be properly terminated inside the user-
supplied flasher. Using figure 2 as a guide, make the
appropriate electrical connections. Ensure that the lines
are adequately fused as shown in figure 2.
3. Connect the black lead to chassis ground.
4. Connect the red wire to the +12VDC supply or
user-supplied flasher (see figure 2).
NOTE
The light assembly can be activated by applying
+12VDC to the red lead. The heavy black lead (-)
must be connected to vehicle ground to perform a
function check.

D. MAINTENANCE.
1. General.
WARNING
Crazing (cracking) of lenses will cause
reduced effectiveness of the light. Do not use
cleaning agents (which will cause crazing)
such as strong detergents, solvents, or
petroleum products. If crazing of lenses does
occur, reliability of light for emergency
signaling purposes may be reduced until
lenses are replaced.
Ordinary cleaning of the plastic lenses can be
accomplished by using mild soap and a soft rag. Should fine
scratches or a haze appear on a lens, they can ordinarily be
removed with a non-abrasive, high quality, one-step,
automotive paste cleaner/wax and a soft cloth.
2. LED Mechanism Replacement.
a. See figure 3. Remove and retain the four
screws which secure the trim ring and lens. Carefully pull
the trim ring and lens straight awaw from the flush mount
light assembly.
b. Remove the three phillips screws which secure
the mechanism. Remove the mechanism by pulling it
straight away.
c. Disconnect the red and black leads at the
quick connect terminals.
