match the LED light output.
· LXEX2F- A dual head (over under) unit. The housing is available in black or
brushed aluminum finish. The sealed cover lens is available in clear or
colored to match the LED light output. Each head is individually controlled.
· LXEX125P-A single head unit. The housing is available in highly polished
aluminum (chrome-like appearance).
· LXEX73P- A dual head (side by side) unit. The housing is available in highly
polished aluminum (chrome-like appearance). For retrofit purposes, the
mounting hole pattern matches the mounting hole pattern of a series 40 (7x3)
perimeter light.
· LXEX64P-A dual head (over under) unit. The housing is available in highly
polished aluminum (chrome-like appearance). For retrofit purposes, the
mounting hole pattern matches the mounting hole pattern of a series 60 (4x6)
perimeter light, and the periphery of the unit matches the periphery of an
OsciLaserTM lens.
In addition to the flashing models, The LED-EX1 is also available in two special function
versions:
The STT (Stop-Turn-Tail) version:
This version can be used as an Auxiliary stop-turn-tail light. When only the power (red)
and ground (black) wire are connected, the light will come on in a reduced intensity steady
burn tail-light mode. Grounding the white wire will result in a bright steady burn mode (stoplight) mode.
The steady-burning (non-flashing) version:
This version can be used as a stand-alone steady-burning light or be flashed with an LED
flasher such as Code 3 PSELED12. This model has only two wires, a power (red) wire
and a ground (black) wire.

WARNING!
If the product is to be used inside the vehicle, it may cause severe personal
injury if not properly mounted and secured. Objects used in vehicle may
become airborne during a collision or other sudden changes in vehicle
speed or direction, such as braking, acceleration or turns.
Wiring:
Flashing Models:
Both single and dual LED-EX modules are equipped with a 8" long 3-wire cable harness
(two for dual modules). The user is required to furnish terminals to attach wires to meet
specific requirement.
Connect wires as follows:
1. Red wire: Power wire, connect to +12V (+24V for 24 volt version) voltage
line.
2. Black wire: GND wire, connect to ground terminal.
3. White wire: Control wire, may be left unconnected. It can also be connected to
GND through a momentary push-button switch, and be used for
programming the operation mode.
Note: The white wire should NOT be connected to a positive voltage
under any circumstances.
Note: It is possible to tie the red wires from both modules, and the black wires
from both modules when wiring the dual modules, provided that a properly
sized wire is used for the common connection. The white wires should not
be wired together if independent programming of the two heads is desired.
Note: The +24V versions will have a 24 volt label designating the unit for
operation on a +24 volt electrical system. The label will typically be
located on the back of the unit.

STT (Stop-Turn-Tail) Models:
These models are equipped with a 8" long 3-wire cable harness. The user is required to
furnish terminals according to his or her preference. Connect the wires as follows:
1. Red wire: Power wire, connect to +12V voltage line.
2. Black wire: GND wire, connect to a ground terminal.
3. White wire: Stop-Light trigger input, grounding this wire will result in high-intensity
operation. This wire may be connected to an active low brake-light trigger
output if available.
Steady-Burning (Non-Flashing) Models:
These models are supplied with only two wires. Red power wire and black GND wire. The
third (white) wire is not available on these models.
Connect the wires as follows:
1. Red wire: Power wire, connect to +12V voltage line.
2. Black wire: GND wire, connect to Ground terminal.
Programming:
Programming the desired flash pattern (or operation mode ) is done with the white control
wire. Y ou can scroll through the eight available flash patterns, by momentarily grounding the
white control wire until you arrive at the desired operation mode. Momentary grounding of
the white wire can be accomplished either by momentarily touching the wire to GND, or
through a momentary push-button switch.
The unit will come on in the default Cycle-flash mode at the time of first power-up, until the
desired flash pattern is programmed. The default flash pattern can then be changed by
programming the desired pattern into the unit, the unit will continue to operate in the same
mode every time the unit is turned off and turned back on. The default flash pattern can be
changed at will for any number of times.
The unit can be reset back to the default flash pattern ( cycle-flash ) by grounding the control
wire for about 8-10 seconds and then releasing it. This can be done while operating in any
of the flash modes.

Note: It is possible to program the two heads on the dual module individually as
shown on page 7. This should be done when a different flash pattern is
desired for each head. The two heads can also be programmed
simultaneously into the same flash pattern by tying the two white control
wires together then programming as shown on page 7.
