SAFETY MESSAGETO INSTALLERS
People’s lives depend on your safe installation 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 equipment.
• 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 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.
• This product contains high intensity LED
devices. To prevent eye damage, DO NOT
stare into the light beam at close range.
• You should frequently 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.
Federal SignalMaster™ Model SMLED2F is an
economical, low wattage, directional light designed

shipping labels, and tags before removing or destroy-
ing them. Ensure that the parts listed in the appro-
priate KIT CONTENTS LIST are included in the
package.

WARNING
These lights are intended for secondary
warning only. They are not intended for use
as a primary warning system.
D. INSTALLATION.
WARNING
When installing equipment inside air bag
equipped vehicles, the installer MUST ensure
that the equipment is installed ONLY in
areas recommended by the vehicle manufac-
turer.
Failure to observe this warning will reduce
the effectiveness of the air bag, damage the
air bag, or potentially damage or dislodge the
equipment, causing serious injury or death to
you or others.

NOTE
For maximum coverage and effectiveness, the
light assembly should be mounted in a
horizontal orientation.
Installation can be accomplished using the
supplied bracket(s) and screws, adhesive pads, or
velcro strips. Determine the mounting position
appropriate for the installation, and then select the
applicable mounting method.
1. Bracket(s)/Adhesive Pads or Velcro Strips.
WARNING
The surfaces to which the adhesive pads (or
velcro strips) are applied must be clean and
dry for proper adhesion. If necessary, use
isopropyl alcohol (rubbing alcohol) and water
to clean the mounting surfaces.
a. Remove the release paper from one side
of the adhesive pad and apply the pad to the bracket
surface. Press the pad firmly against the bracket to
make sure that the pad adheres properly.
b. Peel the release paper from the other side
of the pad and attach the bracket to the mounting
surface. Ensure that the assembly adheres firmly to
the mounting surface.
c. Mounting on a flat non-metallic surface
can also be performed using the supplied velcro hook-
and-loop strips.
d. Secure the light assembly to the mount-
ing bracket(s) using the 1/4" x 1/2" hex head Taptite
screws and lockwashers as shown in figure 1.
2. Bracket(s)/Screws.
a. See figure 1. Use the mounting bracket(s)
as a template and scribe mounting hole position
marks on the mounting surface.
CAUTION
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 dam-
aged; such as brake lines, fuel lines, electrical
wiring or other vital parts.
b. Drill mounting holes at the previously
scribed position marks.
c. Secure the mounting bracket(s) to the
mounting surface with the 1/4" x 5/8" hex head type
B screws.

E. ELECTRICAL.
The light assembly is supplied with a 10-foot
straight cable terminated with a cigar lighter plug. A
flasher PC board is installed at the factory. Addi-
tional wiring is not required. The flasher/light assem-
bly wiring diagram is shown in figure 2.

F. MAINTENANCE.
1. General.
WARNING
Crazing (cracking) of lenses will cause re-
duced effectiveness of the light. Do not use
cleaning agents (which will cause crazing)
such as strong detergents, solvents, or petro-
leum products. If crazing of lenses does occur,
reliability of light for emergency signalling
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 Module Replacement.
a. See figure 3. Remove and retain the two
screws which secure the LED module assembly.
b. Disconnect the right angle connectors and
remove the LED module assembly.
c. Observing polarity, connect the right
angle connectors to the appropriate printed circuit
board connectors.
d. Install the new LED module assembly
using the previously removed screws.

be especially careful.
• This product contains high intensity LED
devices. To prevent eye damage, DO NOT
stare into the light beam at close range.
