Pattern Selection Procedure:

IMPORTANT:

Pattern selection requires the LED to be turned on.

DO NOT LOOK DIRECTLY AT LEDs WHILE UNIT IS IN OPERATION.

Remove the lens and locate the Pattern Activation Pins for your model.

(Section of typical L.E.D. board below shows pins.)

1.

Although the location of the pins varies for each LED board, this

procedure is applicable to all LED boards that offer selectable patterns.
The location of these pins will vary between models, but they will always be
on the LED side of the circuit board.

NOTE:

Turn the LED flasher on.

Use a penny (or any electrical conducting item) to
contact both Pattern Activation Pins for less than 1
second and release. Repeat to go to the next pattern.

Allowing one pattern to run for more than 5 seconds will
make it the default pattern until changed.

Hold a penny against the Activation Pins for more than 1 second and release.
When you've choosen a pattern, turn off the power and re-mount the lens.

Installation: 

1.

Using  the  dimensions  from  the  template,  mark  off  and  drill  the  two  5/16  inch
diameter vent tube holes and the 1 inch wire hole into the mounting surface.

NOTE:

  Make  sure  lighthead  will  not  interfere  with  existing  equipment  and  be

aware of any items on the opposite side of the mounting surface.

2.

Insert the two vent tubes extending from the rear of the lighthead into their holes.
Using a scribe or similar tool, mark off the 4 mounting holes. 

3.

Using  a  drill  bit  sized  for  a  #6  sheet  metal  screw  (and  the  thickness  of  the
mounting surface), drill the four mounting holes. Install a grommet
(customer supplied) into the 1 inch wire hole.

4.

Using appropriately sized wires (Minimum wire size / 18 AWG), run the lighthead
wires  to  their  connections.  (See  Wire  /  Function  Charts)  Fuse  the  +12VDC
connections at 3 Amps and test the operation of the lighthead before securing it
to the vehicle. 

5.

Position the lighthead components onto the mounting surface and secure to the
vehicle using four supplied #6 x 1-1/4” sheet metal screws.

Note: This  product  draws  significantly  less  current  than  a  standard

incandescent  automotive  bulb.  If  your  flasher  does  not  operate
properly,  it  may  be  necessary  to  replace  your  existing  flasher
module with a Whelen 3TERM flasher module. Contact your sales
representative for specific vehicle application.

WARNING! The  outer  surfaces  of  this  product  may  be  cleaned  with

mild soap and water. The use of any other chemicals may
void the product warranty. Do not use a pressure washer.
