INSTALLATION AND WIRING INSTRUCTIONS
FOR
MODEL TCLF2 TRAFFIC CLEARING LIGHT
RETROFIT KIT
A. GENERAL.
Model TCLF2 Retrofit Kit allows easy installa-
tion of the traffic clearing light option in place of the
inboard rotating light mechanism on all Federal
StreetHawk® Light Assemblies. If two traffic clear-
ing light assemblies are desired, a second retrofit kit
must be purchased.
Before attempting installation, insure that the
parts shown in the KIT CONTENTS LIST (para-
graph G.) have been supplied.
B. DOME AND GRILLE REMOVAL
(See figure 1).
1. Turn-off power to Light Assembly.
2. Remove the three (3) #10 hex washer head
thread-forming screws which secure the upper
speaker grille to the lower speaker grille. Lift upper
grille away from lower grille.
3. Remove the eight (four on each side) #8-32 x
7/8 hex head screws from the front and rear edges of
the dome.
4. Carefully remove the domes. Ensure that the
bulkhead gasket remains tucked in its groove.
WARNING
To avoid electrical shock, disconnect the
power cable before performing the installa-
tion procedure.
C. INSTALLATION ON NON-STROBE
UNITS.
To install the traffic clearing light retrofit kit on
a Federal StreetHawk Light Assembly without strobe
lights, proceed as follows:
1. Remove the driver’s side inboard rotating light
mechanism by removing the three (3) screws which
secure the mechanism to the base.
2. Remove the stationary mirror assembly by
removing the screw which secures it to the base.
3. Disconnect the black motor wire at the ground
screw.

4. Disconnect the connector, which secures a
motor wire and a lamp wire, from the terminal block.
Note this terminal block location. It will later be used
when the traffic clearing light is being connected.
5. Position the base plate assembly (supplied) on
the Light Assembly base as shown in figures 2 and 3.
Secure the base plate assembly with three #10 x 1/2
hex head screws (supplied).
6. Secure the traffic clearing light assembly to
the base plate assembly with three (each) 10-32 hex
nuts and #10 flat washers (supplied) as shown in
figure 2.
7. Install the lamp (supplied) in the lamp socket.
8. If two traffic clearing lights are going to be
installed, also perform steps 1 through 7 on the
passenger side of the Light Assembly. See figure 3 for
the mounting location.
D. INSTALLATION ON STROBE UNITS.
To install the traffic clearing light retrofit kit on
a Federal StreetHawk Light Assembly with strobe
lights, proceed as follows:
1. If a single traffic clearing light is going to be
installed, perform steps C.1. through C.7.
2. When two traffic clearing lights are going to
be installed, follow the procedure described in steps
C.1. through C.8. Note that the passenger side base
plate assembly is installed adjacent to the molded
terminal block as shown in figure 4.

E. WIRING INSTRUCTIONS.
After performing the procedure described in this
section, the traffic clearing light will be activated
when the primary rotating warning lights are
switched “on”. To wire the traffic clearing light,
proceed as follows:
1. The lamp lead and “positive” motor lead are
connected in one insulated female quick-disconnect
terminal. Connect this terminal to the same terminal
block position that previously had rotating light
mechanism wires connected (refer to step C.4.). Refer
to figure 3 or figure 4 and note that this is position 4
on the driver’s side terminal block and position 7 on
the passenger side terminal block.
2. On units without the strobe light option
installed, connect the motor ground wire and ground
wire from the traffic clearing light base to the metal
frame of the Light Assembly. This is best accom-
plished by loosening a screw in the pod area, which
exposes the metal frame, closest to the traffic clear-
ing light mechanism. Attach the two wires and re-
tighten the screw (see figure 3).
3. On units with the strobe light option installed,
connect the motor ground wire and ground wire from
the traffic clearing light base to one of the screws
which secure a corner of the strobe power supply to
the metal Light Assembly frame (see figure 4).
F. MIRROR INSTALLATION.
In order to enhance the light pattern, by provid-
ing a reflected flash to the rear, it is necessary to
replace the standard mirrors (removed in step C.2.)
with a new mirror assembly (supplied).
The kit contains a left and a right mirror mount-
ing bracket, a mirror, (2) #4 machine screws, (2) 4-40
hex nuts and a #10 x 3/8 hex head screw. Attach the
mirror to the appropriate mirror mounting bracket
with the #4 screws and nuts. The shiny side of the
mirror should be oriented to the rear at the angle
shown in figure 3 or 4. Use the #10 screw to secure
the mirror bracket to the Light Assembly base.
