Safety Message to Installers and Service Personnel of
Warning Light Equipment
People’s lives depend on your proper installation and servicing of Federal Signal products. It is
important to read and follow all instructions shipped with this product and the original product. 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 prociency in the installation and use of safety warning
equipment.
• Always refer to the vehicle’s service manuals when performing equipment installations on a vehicle.
• 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 effect vehicle operation or mandated safety functions or circuits. Always check the vehicle for
proper operation after installation.
• 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 properly, a separate ground connection must be made. If practical, it
should be connected to the fusible link at the front fender between the negative (–) battery terminal
and chassis ground. 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 the light control so the VEHICLE and CONTROL can be operated safely under all driving
conditions.
• If a seat is temporarily removed, verify with the vehicle manufacturer if the seat needs to be
recalibrated for proper airbag deployment.
• Do not attempt to activate or deactivate the light control while driving in a hazardous situation.
• This product contains high intensity LED devices. To prevent permanent eye damage, DO NOT stare
into the light beam at close range.
• You should frequently inspect the light system to ensure that it is operating properly and that it is
securely attached to the vehicle.
• Do not install equipment or route wiring in the deployment path of an airbag. Failure to observe this
warning will reduce the effectiveness of the airbag or potentially dislodge the equipment, causing
serious injury to you or others.
• 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.

An Overview of the MicroPulse SignalMaster
The Federal Signal MicroPulse SignalMaster is a directional light assembly for use in a ashing mode.
The lens colors available are amber (standard) and red.
The MicroPulse SignalMaster provides two distinctive directional signals: left arrow and right arrow.
In addition, an alternating ash pattern produces a warning signal for use when a directional signal
may not be appropriate.
When a directional signal is selected, the lamps are individually illuminated in a sequential sweeping
motion until all lamps are illuminated. The brake module, which operates independently from the
control module, is located at the center of the lightbar.
These lights are for secondary warning only. They are not for use as a primary warning system.
Failure to use these lights as intended may cause property damage, personal injury, or death.

Installing the MicroPulse SignalMaster Light Assembly
STATIC SENSITIVE DEVICE: The circuitry of the MicroPulse SignalMaster can be damaged or
destroyed by electrostatic discharge (ESD). To prevent ESD, observe anti-static procedures
during installation.
Install the light assembly as described in the instructions included with the mounting kit. Route the
cables to the planned location of the control unit.

Installing the Control Unit and Completing the Wiring
UNIT REQUIRES VENTILATION: The control unit needs to radiate heat. Do not install it in an
area where it cannot dissipate heat into the air. Do not mount the unit near a heater duct or under
the hood.
NOTE: Plan all wiring and cable routing before selecting a mounting location for the control unit.
1. Install the control unit and complete the wiring as described in the instructions included with the
control unit.
REVERSE POLARITY/MISWIRNG: Reverse polarity or incorrect voltage may damage the light. To
avoid damage to the light, ensure that the battery voltage is the same as the voltage rating of the
light and that the correct polarity is observed.
2. Using 18 AWG (minimum) wire, connect the red (+) lead to the positive power source terminal for
the brake module.
3. Using 18 AWG (minimum) wire, connect the black (–) lead to the negative power source terminal
for the brake module.
Removing a Lighthead
1. Remove and retain the two screws that secure the light to the mounting plate (Figure 1).
2. Disconnect the wire harness connector from the cable assembly.

Reinstalling a Lighthead
1. Reconnect the wire harness to the cable assembly.
2. Install the replacement lighthead by securing it with two removed screws. Tightly tighten the
screws so that there is no movement in that lighthead (Ensure that the LED is facing the
upright position.).

Testing the System
LIGHT HAZARD: To be an effective warning device, this product produces bright light that can be
hazardous to your eyesight when viewed at a close range. Do not stare directly into this lighting
product at a close range or permanent damage to your eyesight may occur.
SOUND HAZARD: All effective sirens and horns produce loud sounds (120 dB) that may cause
permanent hearing loss. Always minimize your exposure to siren sound and wear hearing
protection. Do not sound the siren indoors or in enclosed areas where you and others will be
exposed to the sound.
After the installation, test the emergency warning system to ensure that it is operating properly. Also
test all vehicle functions, including horn operation, vehicle safety functions, and vehicle lighting
systems to ensure proper operation. Ensure that the installation has not affected the vehicle operation
or changed any vehicle safety functions or circuits. After testing is complete, provide a copy of these
instructions to the instructional staff and all operating personnel.
Cleaning the Plastic Lenses
CRAZING/CLEANING SOLUTIONS: The use of cleaning solutions, such as strong detergents,
solvents, and petroleum products, can cause crazing (cracking) of the plastic lenses and
reectors.
Failure to follow this warning can damage the lenses and reectors, reducing their effectiveness, and
may result in bodily injury or death to you or others.
1. Rinse the lenses with lukewarm water to loosen dirt and debris.
2. Use a mild soap, lukewarm water, and a soft cloth to gently clean the lenses. To avoid damaging
the lens, do not use heavy pressure or caustic, abrasive, or petroleum-based cleaners.
3. Rinse and dry the lenses with a soft cloth to prevent water spotting.
4. To remove ne scratches and haze, use a specialty plastic cleaner/polish and a soft cloth. You can
also use a high quality automotive paste cleaner/wax that is non-abrasive.
The most effective product you can use for cleaning, protecting, and polishing clear and colored
plastics is Plexus®Plastic Cleaner, Protectant & Polish. Over time, exposure to heat, sunlight, and
smog causes plastic to fade, discolor, scratch, or become brittle. Plexus seals the pores of the plastic,
making the plastic easier to clean, improving scratch resistance, and increasing product longevity.
