A. GENERAL.
WARNING
This unit is designed for use in the lower level
of the Streethawk lightbar only. Do not install
in any other lightbar.
This device is a retrofit LED light head for use in
the Federal Signal Streethawk lightbar. It is designed
to operate on a 12.8 VDC, negative ground system. It
is to be used with flashers designed for use with LED
lights, such as the Federal Signal Intelli-Flash™
Model 650200 Flasher or the Federal Signal FA3C
Flasher. The unit is comprised of an aluminum
mounting bracket with three LED modules installed,
a PCB board with heat sink attached, and a wire
harness.

C. INSTALLATION.
1. To install lower level LED modules when
using the Intelli-Flash Model 650200 flasher, proceed
as follows:
a. Remove the domes.
b. Move or remove any upper level lamp
assemblies that interfere with lower level lamp or
harness access. Rotate rotator worm gears by hand if
mechanism blocks screw access.
c. Service one lamp at a time to avoid
wiring mix-ups. Cut wire ties as needed for connector
access. Remove screws securing lamp to be replaced.
Trace leads back to harness connector and ground
screw and remove. Retain brass spacers and/or
washers for ground screw. Retighten the ground
screw after the old lamp ground connections to the
screw are removed.
d. Place the LED module into position
(electrical connector is at the top) and install the
screws. Take care not to strip the threads in the light
bar base.
e. Route leads to avoid interference, espe-
cially with hot or rotating parts. Plug the LED
module’s red power lead into the existing harness
connector. Make a note of the wire color. Route the
ground wire through the bar to the end where the
main cable enters the bar. Do not terminate at this
time.
f. Repeat for other lamp(s), and then
remove existing flashers and flasher harnesses.
g. Locate the Intelli-Flash flasher near the
terminal strip and secure.

h. To complete the wiring, follow the in-
structions supplied with the flasher.
i. After the flasher is installed and wired,
dress and tie leads.
j. Reinstall any previously removed hard-
ware, and then reinstall the domes.
2. To install lower level LED modules when
using the FA3C flasher, proceed as follows:
a. Remove the domes.
b. Move or remove any upper level lamp
assemblies that interfere with lower level lamp or
harness access. Rotate rotator worm gears by hand if
mechanism blocks screw access.
c. Service one lamp at a time to avoid
wiring mix-ups. Cut wire ties as needed for connector
access. Remove screws securing lamp to be replaced.
Trace leads back to harness connector and ground
screw and remove. Retain brass spacers and/or
washers for ground screw. Retighten the ground
screw after the old lamp ground connections to the
screw are removed.
d. Place the LED module into position
(electrical connector is at the top) and install the
screws. Take care not to strip the threads in the light
bar base.
e. Route leads to avoid interference, espe-
cially with hot or rotating parts. Plug the LED
module’s red power lead into the existing harness
connector. Cut and strip the ground lead to the
necessary length, crimp ring lug and slip over ground
screw. Tighten screw after all grounds to the screw
are in place.
f. Repeat for other lamps, then dress and tie
leads.
g. Replace existing flasher with FA3C
flasher and connect ground wire to chassis ground
screw. Secure flasher.
h. After the flasher is installed and wired,
dress and tie leads.
i. Reinstall any previously removed hard-
ware, and then reinstall domes.
D. TESTING.
WARNING
This product contains high output LED
devices. To prevent eye damage, do not stare
into the light beam at close range
After installation, check the entire system to be
sure the lights are flashing properly and all siren/
light system functions are operating properly.
SAFETY MESSAGETO OPERATORS
People’s 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 operat-
ing 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.

E. MAINTENANCE.
WARNING
Crazing (cracking) of lenses will cause re-
duced effectiveness of the light. Do not use
cleaning agent (which will cause 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.

1. General.
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
soft cloth.
2. PCB Assembly Replacement.
a. Remove the domes.
b. See figure 1. Disconnect the electrical
connector from the PCB assembly.
c. Gently pry the PCB assembly from the
snap-top standoffs on the backplane.
d. Remove the two heat sink retaining
screws and the heat sink.
e. Assembly is the reverse of disassembly.
Prior to installation of the PCB assembly, ensure that
the LED connector pins on the PCB are not bent or
damaged.
3. LED Module Replacement.
a. Remove the domes.
b. See figure 1. Disconnect the electrical
connector from the PCB assembly.
c. Gently pry the PCB assembly from the
snap-top standoffs on the backplane.
d. Remove the device from the light bar.
e. See figure 2. Remove and discard the
Rivscrews retaining the LED module to the
backplane. Remove the LED module.
f. Unlatch the Fresnel lens from the LED
module.
g. Snap the Fresnel lens onto the new
module. Make sure the rectangular recess in the lens
aligns with the black connector on the new LED
module.
h. Position the LED module on the
backplane, aligning the black connector on the LED
with the large clearance hole in the backplane.
Secure the module with the 2 6-32 screws provided.
i. Remainder is the reverse of disassembly.
4. Fresnel Lens Replacement.
Same as LED Module Replacement above,
except that the Rivscrews must be retained for reuse
if a new LED module is not being installed.
