MOUNTING

Important: DO NOT over tighten
mounting screws or nuts. This could
cause permanent damage to the light.

1. Locate flat mounting location for the
LED3 Light.

2. When the position of LED3 is
determined use paper template on
next page to drill hole locations. Screw
mounting holes should be drilled using
a 3/32” drill bit. Wire entry holes
should be drilled using a 1/4” drill bit.

3. Make electrical connections.

4. Using supplied #6 x 3/4” screws, fasten
LED3 to mounting surface. Be sure
not to overtighten screws as this will
cause hole in mounting surface to strip
out. Be sure that supplied gasket is
mounted between mounting surface
and LED3.

1 LIGHT

Single Light Operation: Follow the ID Selection steps and set the LED3 to ID#1
if it is not already. NOTE: Steady Burn is produced for patterns 9 & 10 in Single
Operation.

2 LIGHTS

ALTERNATING: To obtain Alternating patterns, follow the ID SELECTION steps

and set one LED3 to ID#1 and the other to ID#3. Then proceed to the
PATTERN SELECTION steps.

SIMULTANEOUS: To obtain Simultaneous patterns, follow the ID SELECTION steps and set both LED3 lights to
ID#1. Then proceed to PATTERN SELECTION steps.

4 LIGHTS

X-Pattern: To obtain X-patterns, follow the ID SELECTION steps and set one of the four LED3 lights to ID#1, one

to ID#2, one to ID#3, and one to ID#4. Then proceed to PATTERN SELECTION steps. NOTE: Be sure to mount
each LED3 in the correct placement based on ID#.

2. Turn LED3 ON.

3. Momentarily touching and removing the WHITE
wire(s) to ground will advance the LED3 to the next
flash pattern. Touching and removing the White wire
for more than a few seconds will allow you to change
the LED3 to the previous pattern. See flash pattern
table. Continuing to touch and remove the WHITE
wire(s) to ground will allow you to scroll through the
pattern list. After pattern #33 is reached the list will
start over again at pattern #1.

NOTE: The LED3 is equipped with flash pattern

memory. Once you have selected a pattern the LED3
will always activate to that pattern every time the unit
is turned on. Tape up and secure WHITE wire so that
it will not accidentally change your selected pattern.

PATTERN RESET

1. Remove power.

2. Place WHITE (sync) wire to ground.

3. With sync wire grounded, re-power RED wire.

4. Maintain for one second (light will dim).

5. Remove power and ground (pattern 1 set).

the output of a +10-16Vdc switching flasher.

NOTE: The LED3 is a factory sealed unit that

CANNOT be serviced in the field. Any attempt to gain
access to the LED3 unit will most likely cause
permanent damage and void its warranty.
