Installation and Maintenance Instructions
Model QuadraFlare DOT
Installing the QuadraFlare
INSTALL IN RECOMMENDED AREAS: When installing equipment
inside airbag equipped vehicles, the installer MUST ensure that
the equipment is installed ONLY in areas recommended by the
vehicle manufacturer.
Failure to observe this warning reduces the effectiveness of the
airbag, damage the airbag, or potentially damage or dislodge the
equipment, causing serious injury or death to you or others.
NOTE: For maximum coverage and effectiveness, mount the light
assembly in a horizontal orientation (see Figure 1).
Before proceeding with installation, determine the approximate
location of the light assembly and plan all cable/wire routing.
To install the QuadraFlare, proceed as follows:
1. See Figure 1. Position the QuadraFlare Warning Light
assembly on the desired mounting surface. Ensure that the
unit is level side to side. Using the dimensions provided in
Figure 2, scribe the four mounting hole locations and a wiring
routing hole location on the mounting surface.
DAMAGE TO LIGHT: When installing the QuadraFlare light on a
vehicle, you MUST use the manufacturer’s supplied screws and
screw grommets. Do not use an impact drill or an electric screw
gun when installing the light. Torque the mounting screws to
the manufacturer’s recommended specication of 12 in-lb +/-10
percent.
Failure to observe these precautions damages the light and void
any warranty claims for the light.
DRILLING PRECAUTIONS: Before drilling holes in ANY part of a
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.

Installation and Maintenance Instructions
Model QuadraFlare DOT
2. Drill four 1/4" (0.250") mounting holes and a wire routing
hole 1" (1.00") at the previously scribed locations.
3. Install the four supplied rubber rivet nuts into the four 1/4"
mounting holes.
NOTE: When removing the QuadraFlare Warning Lights, inspect
the mounting grommets for wear and replace them as needed.
DRILLING PRECAUTIONS: All drilled holes should be free of
burrs and sharp edges. Grommet (user supplied) all wire routing
holes and/or sealed to avoid wire and/or vehicle damage.
4. The QuadraFlare Warning Light assembly has two or three
12" long lead wires, which exit out the back of the unit, for
making electrical connections.
5. Complete the electrical connections as described in the Wiring
the QuadraFlare section.
6. See Figure 1. Align the QuadraFlare Warning Light assembly
with the previously inserted rubber rivet nuts and secure with
the provided #6 x 2.0" S.S. screws.
NOTE: QuadraFlare models have identiable color-coded sticker
dots located on the backside of the light assembly. The color-coded
sticker dots correspond to the LED colors on the PC board.
The rst letter in the model number extension “_XX” is the color
that activated by the red wire. The second is activated by the white
wire.
Never apply power to both red and white wires. Both colors will
illuminate incorrectly.
Wiring the QuadraFlare
The Model QuadraFlare Warning Light assembly operates on
12 Vdc. Five 12-inch long lead wires are supplied for making
electrical connections to the QuadraFlare Warning Light assembly.

7
Installation and Maintenance Instructions
Model QuadraFlare DOT
Ensure that all wires are properly connected and insulated
appropriately.
To make electrical connections, proceed as follows:
1. Using 18-gauge (minimum) wire, connect the red (+) lead to
the positive power source terminal and the black (–) lead to
the negative power source terminal at the asher.
2. For pre-terminated models, plug connector to the cable.
Safety Message to Operators
Peoples’ lives depend on your safe use of our products. Listed
below are some important safety instructions and precautions
you should follow:
• Although your warning system is operating properly, it may
not be completely effective. People may not see or heed your
warning signal. You must recognize this fact and continue
driving cautiously.
• Also, situations may occur which obstruct your warning
signal when natural or man-made objects are between your
vehicle and others, such as: raising your hood or trunk lid. If
these situations occur, be especially careful.
• This product contains high intensity LED devices. To prevent
eye damage, DO NOT stare into the light beam at close
range.
• At the start of your shift, you should ensure that the light is
securely attached and operating properly.
Failure to follow these safety precautions may result in property
damage, serious injury, or death to you, to passengers, or to
others.
Retain and refer to this message.

Installation and Maintenance Instructions
Model QuadraFlare DOT
Cleaning the QuadraFlare
CLEANING POLYCARBONATE DOMES AND LENSES: Crazing
(ne cracks) of lenses causes reduced effectiveness of the light.
Do not use cleaning agents (which causes 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.
CLEANING POLYCARBONATE DOMES AND LENSES: To extend
the life of this device, periodic cleaning is necessary. Clean the
lens/dome with a mild, non-abrasive, neutral-pH cleaning agent
and a soft, clean cloth. Rinse the device thoroughly to ensure
that no cleaning agent residue remains. To avoid water spots,
dry the device with a soft clean cloth.
Failure to follow this precaution can cause crazing or cracking of
the lens/dome and voids the warranty claims for the light.
NOTE: Scratched or dull reector, mirrors or lenses reduces the
effectiveness of the lighting system. Use a mild, non-abrasive,
neutral-pH cleaning agent and a soft, clean cloth, when cleaning
the lighting system. Replace any optical components that may
have been scratched or crazed during system installation. The use
of strong, non-neutral-pH cleaners voids the warranty.
