A. GENERAL.
The Cuda TriOptic Models 352012 and 352022 are LED
light heads designed for use in conjunction with all ederal
Signal switch controllers. These light heads are designed for
mounting on a vehicle’s interior, exterior, or on a motorcycle.
The housing is comprised of an extruded aluminum profile
with a front high-impact polycarbonate protective lens. The
unit is supplied with mounting hardware and a five-foot cable.
This unit has an operating temperature of -30°C to +65°C
(-22° to +149°). It may be mounted in the horizontal or
vertical position with the cabling exiting from either side or
the rear. The physical dimensions of the 352012 are 4.2-inches
long by 1.6-inches deep by 2.4-inches high. The 352022 is 7.9-
inches long by 1.6-inches deep by 2.4-inches high. End caps
and the front lens cover are compression sealed to the ex-
truded housing by means of Buna-N gasketing. The unit also
features stainless steel hex machine screws and kepsnuts for
the channels on the top, bottom and rear of the housing.
The Cuda TriOptic is programmed with eight flash
patterns selectable by a control lead. The light head can also be
user-configured to operate with an external flashing device.
The 352012-02E and 352012-04E have been configured, at the
factory, for external flasher control..
B. INSTALLATION.
WARNING
This product is intended for supplemental
warning and for use in conjunction with an
approved primary warning light system.
Consult local codes and regulations to deter-
mine if the power supply/ light head combina-
tion complies with the horizontal or vertical
mount positioning desired in your application.
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 manufacturer.
Failure to observe this warning will reduce the
effectiveness of the air bag, damage the air bag,
or potentially damage or dislodge the equip-
ment, causing serious injury or death to you or
others.
NOTE
or adequate condensate drainage, a horizontally
mounted unit MUST be mounted with the two drain
holes facing down (see figure 1). or vertical mount-
ing, the drain holes are located conveniently on either
end of the housing such that the cabling may be
routed from top or bottom.
Determine which side of the unit will be attached to the
mounting surface and which direction the power cable enters
the unit.
See figure 2. The unit is supplied with the power cable
entering the left rear position. To change the cable entry to the

left end, remove the left end cap and gasket. Remove the
rubber plug from the hole in the cap and route the cable and
grommet through both the gasket and the end cap. Position the
grommet properly around the cable and in the end cap. Place
the rubber plug that was removed from the end cap into the
rear of the housing to seal the hole where the cable used to
enter the unit. Slide the #8-32 x 1/2 hex head screws into the
desired channel and replace the gasket and end cap. Ensure
the flat head screws are properly tightened for a good seal.
To change the cable entry to the right end or rear, remove
the end caps and the 6-32 x 1/2" screw(s) and lockwashers(s)
from the rear of the unit. Slide the circuit board assembly from
the housing and back into the opposite end of the housing.
Remove the appropriate rubber plug and route the cable and
grommet accordingly. Place the rubber plug that was removed
into the remaining hole. Install the 6-32 x 1/2" screw(s) and
lockwashers(s) into the back of the unit and secure. Slide the
#8-32 x 1/2 hex head screws into the desired channel. Install
the gaskets and end caps and tighten the flat head screws
securely.
CAUTION
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.
A 3/16" diameter mounting hole is recommended for the
two #8 x 1/2" mounting hardware screws. In addition, two #8
keps nuts are also provided for securing the assembly to the
mounting surface.
CAUTION
Install the light head in an adequately ventilated
area. Never install near heater ducts.
CAUTION
After prolonged operation, the unit gets hot and can
cause burns. Do not hold the unit in your hands for
extended periods of time. Do not touch the unit
during, or shortly after, operation. Always allow the
unit to cool before handling.
C. ELECTRICAL SPECIFICATIONS AND FEATURES.
NOTE
Powering multiple devices with a common control lead
may cause one or more units to briefly remain
functional after signal power is removed. or example,
due to the high input filter capacitance, a strobe
supply can briefly supply the current required to
operate a low current device such as a Cuda
TriOptic™. If necessary, use a relay to isolate devices
with large filter capacitors. See figure 3 for the
schematic; all components/wires are user-supplied.
The unit is intended to operate on a 12.8 VDC system. It
includes a 3 conductor connecting cable housed in a black
jacket. The 3 conductors are: red (positive), black (negative)
and green (switching). This unit is intended to work in
conjunction with all ederal Signal switch controllers.
1. Standard Operation.
The single head unit (Model 352012) features 8 flash
patterns that are selected by applying the switching wire
(green) to the ground wire (black). These wires are all within
the black cable attached to the unit. The flash patterns are as
follows:
a. Steady On
b. 120 PM
c. 165 PM
d. 240 PM
e. 300 PM
f. Combo 1:
4 intervals @ 120 PM
10 intervals @ 300 PM
g. Combo 2:

l. Alternating quad flash.
m. “BLANK” (off) pattern: to indicate the end.
After the desired pattern has been selected, the green
wire must be connected directly to the red power lead.
This unit is designed to return to the last flash pattern
selected before it was de-energized. or example, if the unit is
de-energized at the seventh flash pattern and then re-
energized, the seventh flash pattern illuminates. However,
there is a two-second delay for the unit to remember the last
pattern. So, if the unit is energized and functioning on the
third flash pattern and the unit is switched to the fourth flash
pattern and de-energized within a two second time limit, the
unit will return to the third flash pattern.
2. External Flashing Device Operation.
The 352022 and 352012 can be user modified to
operate with an external flashing device. It can be either
ground side, or high side, activated.
a. Remove the end cap and printed circuit board
assembly as shown in figure 2.
b. Move JP1, JP2, and JP3 (Model 352022 only) to
the external position (see figure 4).
c. Replace the printed circuit board assembly and
end cap.
d. Ensure that the drain hole is facing down and
reassemble the light head into the housing without bunching
the wire.
e. or a high side activated flasher, install a 3-
ampere fuse in the Cuda TriOptic red wire and connect to the
control lead on the flasher. Connect the black wire to ground.
Connect the green wire to the Cuda TriOptic red wire.
f. or a low side activated flasher, install a 3-
ampere fuse in the Cuda TriOptic red wire and connect to a
12V source. Connect the green wire to the red wire. Connect
the black wire to the control lead on the flasher.
