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 instructions
shipped with the products. In addition, listed
below are some other important safety in-
structions and precautions you should follow:
• To properly install lighting system, you
must have a good understanding of auto-
motive systems, along with proficiency in
the installation and use of safety warning
equipment.
• This product contains high intensity LED
devices. To prevent permanent eye dam-
age, DO NOT stare into the light beam at
close range.
• DO NOT install equipment or route wir-
ing 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.
• A light system is a high current device. In
order for it to function properly, a sepa-
rate ground connection must be made. If
practical, it should be connected to the
negative battery terminal. At a minimum,
it may be attached to a solid metal body
or chassis part that will provide an ef-
fective ground path as long as the light
system is used.
• Locate the light system controls so the
VEHICLE and CONTROLS can be oper-
ated safely under all driving conditions.
• The mounting system should be periodi-
cally inspected to ensure that it is secure-
ly 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.

mounting hardware. It has an operating temperature range
of -40°C to +65°C.

not attempt to install or operate it. File a claim immedi-
ately with the carrier, stating the extent of damage. Care-
fully check all envelopes, shipping labels, and tags before

D. INSTALLATION.
NOTE
Installation can be accomplished using the sup-
plied hardware. The light heads come with AMP
or Weather-Pack connectors and may be used with
the appropriate Federal Signal Ricochet® Cable
Kits. The basic light functions of the unit must be
controlled by a user-supplied Federal Signal Cor-
ner LED electronic flasher, Model 501903.
Before drilling holes in ANY part of 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.
Connecting these LED light heads to a strobe
power supply will result in immediate failure of
the LED light heads and may damage the strobe
power supply.
1. Following the directions in the vehicle manufac-
turer’s service manual, remove the rear panel containing
the back-up lamp assemblies. Remove the back-up lamp
sockets.
2. Cut-out the included hole template. See figure 1.
Position the template so that the smaller hole is centered
on the hole for the back-up lamp socket. Mark the center of
the 1-1/2” diameter hole.

3. To aid cutting, remove the boss surrounding the
vent hole then using a hole saw, drill the 1-1/2” hole at a
45-degree angle as shown in figure 1.
4. See figure 2. Position the LED light head as shown
and mark the two small holes. Drill the two small holes
with a 5/32” drill. Deburr all the holes then thoroughly
clean the housing to remove all chips.
The surfaces to which the adhesive gasket is ap-
plied must be clean and dry for proper adhesion. If
necessary, use isopropyl alcohol (rubbing alcohol)
and water to clean the mounting surface.
5. Peel the backing from one side of the gasket and
apply the gasket to the LED light head. Peel the remaining
backing and insert the LED light head into the housing.
Do not over-tighten the screws.
6. Install the supplied screws using care not to cock
the LED light head.
7. Seal the perimeter of the LED light head with
RTV (user-supplied) to maximize moisture protection.

SAFETY MESSAGE TO OPERATORS
People’s lives depend on your safe use of our
products.
Listed below are some important safety in-
structions and precautions you should follow:
• Although your warning system is operat-
ing properly, it may not be completely effec-
tive. People may not see or heed your warn-
ing 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.
• 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.
