Safety First

This document provides all the necessary information to allow your Whelen product to be properly and safely installed.
Before beginning the installation and/or operation of your new product, the installation technician and operator must
read this manual completely. Important information is contained herein that could prevent serious injury or damage.

• 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.

• If this manual states that this product may be mounted with suction cups, magnets, tape or Velcro®, clean the
mounting surface with a 50/50 mix of isopropyl alcohol and water and dry thoroughly.

• 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.

• If this product uses a remote device to activate or control this product, make sure that this control is located in
an area that allows both the vehicle and the control to be operated safely in any driving condition.

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

• This product contains either strobe light(s), halogen light(s), high-intensity LEDs or a combination of these
lights. Do not stare directly into these lights. Momentary blindness and/or eye damage could result.

• Use only soap and water to clean the outer lens. Use of other chemicals could result in premature lens cracking
(crazing) and discoloration. Lenses in this condition have significantly reduced effectiveness and should be
replaced immediately. Inspect and operate this product regularly to confirm its proper operation and mounting
condition. Do not use a pressure washer to clean this product.

• It is recommended that these instructions be stored in a safe place and referred to when performing
maintenance and/or reinstallation of this product.

• FAILURE TO FOLLOW THESE SAFETY PRECAUTIONS AND INSTRUCTIONS COULD RESULT IN DAMAGE TO
THE PRODUCT OR VEHICLE AND/OR SERIOUS INJURY TO YOU AND YOUR PASSENGERS!

Installation and Wiring:

Caution: Permanent mounting of this product will require
drilling. It is absolutely necessary to make sure that no other
vehicle components could be damaged by this process.
Check both sides of the mounting surface before starting. If
damage is likely, select a different location.

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 FUSED

at
the battery to carry that load. DO NOT USE CIRCUIT
BREAKERS WITH THIS PRODUCT!

NOTE: The color of the Positive Wire is determined by the
color of the LED. In this manual, RED is used as a reference
color.

1. Using the dimensions shown, mark the 2 mounting hole

locations and wire access hole location onto the mounting
surface.

2. Drill the two, 0.250” diameter mounting holes and a 0.625”

(minimum) wire access hole into the mounting surface.

3. Place the gasket into position on the rear of the M7

assembly. Insert the slotted hole screw grommet through the
mounting holes on the M7/Gasket assembly.

4. Feed the M7 wires through the wire access hole in the

mounting surface. Press the M7/Gasket/Grommet assembly
onto its mounting location so that it is flat against the
mounting surface. With the assembly in position and using
the hardware provided, tighten the mounting screws until the
lighthead assembly is drawn firmly against the mounting
surface. DO NOT OVERTIGHTEN!

5. Using appropriately sized wires (minimum 18 AWG), extend

the M7 wires to their designated connections. Refer to the
diagram below for wiring and fusing information.

Operation:

Flash Mode / RED:

Apply +12V to the RED wire to activate the lighthead in “flash
mode”. With flash mode activated, you may change the flash
pattern using Scan-Lock™.

SYNC / GREY

To SYNC two lightheads, configure both lightheads to display the
same Phase 1 (Simultaneous) pattern. Turn the power off and
connect the GREY wire from each lighthead together. When the
lightheads are activated their patterns will be synchronized. To
configure two lightheads to alternate their patterns, advance the
pattern of either lighthead to Phase 2 (Alternating) of the current
pattern.

Scan-Lock™ / WHT/VIO / Flash Pattern Selection:

This feature allows the user to select from several available flash
patterns. The lighthead must be switched on for Scan-Lock™ to
work.

TO CYCLE THROUGH ALL PATTERNS: Apply positive voltage
to the WHT/VIO wire for less than 1 second and release. To cycle
backward through patterns apply positive voltage to the WHT/VIO
wire for over 1 second and release.

TO SET A PATTERN AS DEFAULT: Allow the pattern to run for
more than 5 seconds. The lighthead will flicker slightly when the
pattern locks in. This flicker may be difficult to see with some
patterns. The lighthead will now display this pattern when
activated.

TO RESET TO THE FACTORY DEFAULT PATTERN: Turn off
power. While applying positive voltage to the WHT/VIO wire, turn
power on. This will reset the lighthead to it’s factory default flash
pattern.

IMPORTANT! It is the responsibility of the installation
technician to make sure that the installation and operation of
this product will not interfere with or compromise the
operation or efficiency of any vehicle equipment!

IMPORTANT WARNING!

CAUTION! DO NOT LOOK DIRECTLY AT THESE LEDS WHILE THEY ARE ON.
MOMENTARY BLINDNESS AND/OR EYE DAMAGE COULD RESULT!
