FEDERAL ALL LIGHT STREETHAWK® LIGHT ASSEMBLY
SAFETY MESSAGE TO INSTALLERS
WARNING
People’s lives depend on your safe installation of
our products. It is important to read, understand
and follow all instructions shipped with this
product and the related add-on 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 profi-
ciency 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. Remove all
burrs from drilled holes. To prevent electrical
shorts, grommet all drilled holes through
which wiring passes.
• A light system is a high current device. In
order for it 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 is to be used.
• This product may contain high intensity LED
devices. To prevent eye damage, DO NOT stare
into the light beam at close range.
• High voltages are present inside the strobe
light equipped models during and after
operation. Ensure that power is disconnected
and wait at least ten minutes before removing
the dome.
• Locate light system controls so the VEHICLE
and CONTROLS can be operated safely under
all driving conditions.
• 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 instruc-
tions may result in property damage, serious injury, or
death to you or others.
I. GENERAL.
The light assembly comes from the factory with ten (10)
stationary light lenses, gaskets, and mounting hardware in kit
form. This enables the user to choose and install the color
combination that best suits the application.
WARNING
Using a lens colored differently than an LED will
greatly reduce the light output, thereby reducing
the effectiveness of the light for emergency
signaling purposes. Either use a clear lens or
match the color of the lens with the LED.
Federal recommends that lenses be installed prior to
mounting the light assembly on the vehicle. To install a lens in
any position, proceed as follows (see figure 5):
A. Install gasket on rim of lens.
B. Insert lens and gasket into lens opening. Secure with two
#6 screws. Tighten to 10-15 in./lbs. of torque.
II. ELECTRICAL WIRING.
A. General.
The Light Assembly is completely wired at the factory
and does not require any additional internal wiring. (If desired, to
allow Intelli-Flash Mode 2, connect the wht/red Intelli-Flash wire
to an unused power cable wire or a user-supplied wire.) The cable
connected to the Light Assembly contains all the conductors
necessary for proper control of all basic and optional functions (see
figure 1).
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.
Figures 6 and 7 illustrate the external/internal Light
Assembly wiring by function. Using figures 1, 6, and 7 as a guide,
make the appropriate electrical connections shown in Table 1. Be
sure to use fuses (current ratings shown in the applicable diagram
in figures 6 and 7), wire and switches with adequate current
capacity for each function.
NOTE
Any of the light assembly functions can be activated by
applying 12VDC to the appropriate control line. The
heavy black lead (-) must be connected to vehicle ground,
to perform a function check.
B. Programming the Intelli-Flash (see figure 7).
To operate the flasher in Mode 1, close SW1. To operate
the flasher in Mode 2, close SW1 and SW2.
Turn on the flasher in Mode 1. Short across the program-
ming pins until the desired pattern is running. Allow the pattern
to run for at least 15-seconds to program Mode 1.
Turn on the flasher in Mode 2. Short across the program-
ming pins until the desired pattern is running. Allow the pattern
to run for at least 15-seconds to program Mode 2.

III. NFPA INSTALLATION.
MESSAGE TO NFPA INSTALLERS
For mounting, color configuration, and mounting
considerations, refer to the latest edition of the NFPA
standard for automotive fire apparatus.
For Models FHL4856R, FHL4856W, FHL4857R, FHL4857W,
SHL4856, SHL4857, and SHL4858, use figure 2 and table 2 as a
guide (for mounting and wiring) when installing this light
assembly as part of an NFPA certified system.
IV. MAINTENANCE.
A. Cleaning the Plastic Domes and Lenses.
WARNING
Crazing (cracking of domes or 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 domes or
lenses does occur, reliability of light for emergency
signaling purposes may be reduced until domes or lenses
are replaced.
Ordinary cleaning of the plastic domes and lenses can be
accomplished by using mild soap and a soft rag. Should fine

scratches or a haze appear on the domes, they can ordinarily be
removed with a non-abrasive, high quality, one-step, automotive
paste cleaner/wax and a soft cloth.
B. Lamp Replacement.
WARNING
A serious injury may result if lamp is touched when hot.
Always allow lamp to cool before removing. Halogen
lamps are pressurized and if broken can result in flying
glass. Always wear gloves and eye protection when
handling the lamps.
1. Dome Removal (see figure 3).
a. Turn-off power to Light Assembly.
b. Remove four #8-32 x 7/8" hex head screws
which secure the center dome to the center base. Lift center dome
away from center base.
c. Remove the eight (four on each side) #8-32 x 7/
8" hex head screws from the front and rear edges of the dome.
d. Carefully remove the domes. Ensure that the
bulkhead gasket remains tucked in its groove.
e. The domes can be replaced by reversing the
procedure. Torque dome screws to 14-18 in./lbs.
2. Primary Rotating Lamps.
To replace the halogen lamp, proceed as follows (see
figure 4):
CAUTION
Forced rotation of the light mechanism will cause
damage to the worm gear. ALWAYS rotate the light
mechanism by rotating the motor shaft.
a. Rotate the reflector until the lamp clip (located
at the base of the lamp) can be removed, and remove the clip by
sliding it away from the reflector.
b. Note the lamp’s orientation and pull the
defective lamp and connector out of the socket.
CAUTION
When installing a new lamp, do not touch the glass
portion. If the glass has been touched, shortened lamp
life will result. If the glass end has been handled, it
should be carefully cleaned with a grease solvent.
c. Replace the defective lamp with a new H-1
halogen lamp (Part No. 8440A265A). When reassembling, ensure
that the lamp is secured to the connector and that the clip is
properly seated in the grooves on the lamp socket.
3. Secondary Lamps.
To replace lamps in the secondary light positions
(ten locations), proceed as follows (see figure 5):
a. Remove the two #6 pan head screws and
washers.
b. Remove lens by pulling straight out. Remove
