flasher does not operate properly, use a Whelen® flasher.

Using the information shown below, mark 2 mounting holes and a wire access hole
location onto the mounting surface.

Drill two 1/4" diameter mounting holes and a 5/8" (minimum) wire access hole in the
mounting surface.

Install the round hole screw grommets (supplied) into these mounting holes. Select the
gasket appropriate for your installation. Use the formed gasket when mounting to a
smooth, flat surface.

Use the adhesive-backed gasket for all other installations.

Adhere the gasket onto the lighthead so that it is centered and completely flat against the
rear surface of the lighthead.

Using appropriately sized wires (minimum 18 AWG), extend the lighthead wires to their
connections. Refer to the illustration for wiring and fusing information.

Position the lighthead onto the mounting surface and secure to the vehicle using the two
supplied #8 sheet metal screws.

:

Apply +VBAT to the RED wire to activate the lighthead in “flash mode”. In flash mode, you
may change the flash pattern using Scan-Lock™.

The type of switch used depends on how the operator wishes Low Power to function.

By applying +VBAT to the VIO wire for less than 1 sec., the lighthead is

“latched” into low power. The unit must be turned off and then back on to restore normal
operation.

Applying +VBAT to the VIO wire for more than 1 sec. holds the lighthead in

low power mode until voltage is removed.

This feature allows the user to select from

several available flash patterns. Lighthead must be switched on for Scan-Lock to work.

Apply +VBAT to the WHT/ VIO wire for less than 1

second and release. To cycle backward through patterns apply +VBAT to the WHT/VIO wire
for over 1 second and release.

Allow the pattern to run for more than 5 seconds. The

lighthead will now display this pattern when active.

Turn off power. While applying +VBAT

to the WHT/VIO wire, turn power on. The lighthead will reset to its default pattern.

To SYNC 2 lightheads, configure both lightheads to display the same Phase 1

(Simultaneous) pattern. Turn power off and connect the GREY wire from each lighthead
together. Activate the lightheads and their patterns will be synchronized. To configure 2
lightheads to alternate their patterns, advance either lighthead to Phase 2 (Alternating) of the
current pattern.

(A momentary switch is preferred)

Proper installation of this product requires the installer to have a good understanding of
automotive electronics, systems and procedures.

Failure to use specified installation parts and/or hardware will void the product warranty!

If mounting this product requires drilling holes, the installer MUST be sure that no vehicle
components or other vital parts could be damaged by the drilling process. Check both
sides of the mounting surface before drilling begins. Also de-burr any holes and remove
any metal shards or remnants. Install grommets into all wire passage holes.

Do not install this product or route any wires in the deployment area of your air bag.
Equipment mounted or located in the air bag deployment area will damage or reduce the
effectiveness of the air bag, or become a projectile that could cause serious personal
injury or death. Refer to your vehicle owner's manual for the air bag deployment area. The
User/Installer assumes full responsibility to determine proper mounting location, based
on providing ultimate safety to all passengers inside the vehicle.

For this product to operate at optimum efficiency, a good electrical connection to chassis
ground must be made. The recommended procedure requires the product ground wire to
be connected directly to the NEGATIVE (-) battery post.

Do not attempt to activate or control this device in a hazardous driving situation.

WARNING! All customer supplied wires that connect to the positive (+) terminal of the

battery must be sized to supply at least 125% of the maximum operating current and

“at the battery” to carry that load. DO NOT USE CIRCUIT BREAKERS WITH THIS

PRODUCT!
