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.

• 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!

Mounting...

Position the housing onto the mounting surface in the proposed
mounting location. The mounting surface used must be perfectly
flat. This will determine the exact mounting location and allow the
installer to determine the most appropriate mounting style for their
specific installation.

Mounting Style #2 is best suited for applications where there is
access to the backside of the mounting surface. The style
requires 4, 1/4-20 Hex Head bolts, split-lock washers and nuts
(customer provided). Bolts should be of a length appropriate for
your specific installation.

Note: As mounting 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.

The housing may be secured to the vehicle in one of two styles:

Mounting Style #1 is best suited for applications where there is
limited access to the backside of the mounting surface. The style
requires four, 1/4” x 1 1/4” phillips pan head sheet metal screws
(included)

1. Using the housing in its mounting location as a guide, scribe
the mounting surface behind the 4 areas shown using an awl or
suitable tool.

2. Remove the housing. Using a drill bit sized for 1/4” sheet
metal screw and the thickness of the mounting surface, drill four
mounting holes in the areas marked in the previous step.

3. Drill appropriately sized wire passage hole into the mounting
surface. A good location for this hole is between the top lighthead
and the top of the housing. De-burr this hole and install an
appropriately sized grommet.

4. Using appropriately sized wire, extend the wires for each
lighthead through the housing, though the wire passage hole and
to their ultimate destinations for power, ground, switch control,
etc.

5. Position the housing/gasket assembly onto the mounting
surface. Confirm that the lighthead wires are not being pinched
and that the mounting gasket is properly seated onto the housing
and in full and proper contact with the mounting surface. Secure
the housing to the mounting surface using the hardware
previously indicated.

6. Complete the wire connections using the information
provided in the lighthead manual.

IMPORTANT! Before returning the vehicle to active service,
visually confirm the proper operation of this product, as well
as all vehicle components/equipment.
