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.

IMPORTANT! The lightbar should be a minimum of 16" from any radio
antennas!

Permanent Mounting:

1. Locate the mounting foot and mounting plate included with your lightbar. If not already present,
install the mounting plate onto the mounting foot. When properly positioned, this plate is centered
from side-to-side on the mounting foot.

2. Flip lightbar upside-down to expose bottom of extrusion and place mounting foot onto extrusion.

3. Rotate the mounting foot 90° in a counter-clockwise direction. Make sure that the edges of the
mounting foot swing into position under the extrusion mounting lip.

4. Repeat this procedure for the remaining mounting foot and return the lightbar to its right side-up
position.

5. Position the lightbar onto the vehicle roof in the desired mounting location. One often selected
location is directly above the B-pillars. This area is the strongest part of the roof. Refer to your
lightbar manual for your lightbars cable exit location, to be sure that the lightbar is facing the proper
direction.

6. Adjust the two mounting feet outwards so that they are as close to the edge of the roof as possible.
Make sure that both mounting feet are in full contact with the roof (See below). Be sure that there is
no less than 1/2” clearance between the roof and the lightbar at their closest point. When the
mounting feet are in their proper position, lightly tighten the mounting foot allen head set screws.

7. Turn the lightbar upside-down and firmly tighten all of the set screws from step 6 (2 or 4 per side).

8. Note that on the adjustable foot, use the hole in the pad as a guide to drill the two holes into the
mounting foot at the locations shown.

9. Place the lightbar in its final mounting position on the vehicle, mark
the mounting hole locations off onto the mounting surface, remove
the lightbar and drill the mounting holes.

10. Place the lightbar back onto the vehicle lined up with the mounting
holes and secure the mounting feet to the vehicle using the supplied
hardware.

width as the vehicle roof. If too large or small it will not mount properly
and may come loose during driving.

Slide Bolt Mounting (Permanent):

1. Position the slide bolt mounting plates onto the bottom of the lightbar extrusion. These plates rotate into position the same way as the mounting foot. Position the plates as
far outward as possible (if a 3rd mounting plate is used, it should be positioned under the center of the lightbar).

2. Secure the plates to the extrusion using the set screws provided.

3. Position the lightbar onto the vehicle and mark the mounting bolt locations. Drill the necessary mounting holes using an appropriately sized drill bit sized for a 1/2” bolt.

Strap Mounting:

1. Locate the mounting foot, mounting plate and tinnerman plate included with
your lightbar. If not already present, install the mounting plate onto the
mounting foot. When properly positioned, this plate is centered from side-to­side on the mounting foot.

2. Flip the lightbar upside-down to expose the bottom of the extrusion and place
the mounting foot onto the extrusion.

3. Rotate the mounting foot 90° in a counter-clockwise direction. Make sure that
the edges of the mounting foot swing into position under the extrusion
mounting lip. Install a tinnerman plate onto the extrusion in the same manner.

4. Repeat this procedure for the remaining mounting foot and tinnerman plate and
return the lightbar to its right side-up position.

5. Position the lightbar onto the vehicle roof in the desired mounting location. One
often selected location is directly above the B-pillars. This area is the strongest
part of the roof. Refer to your lightbar manual for cable exit location, to be sure
that the lightbar is facing the proper direction.

6. Adjust the two mounting feet outwards so that they are as close to the edge of
the roof as possible. Both mounting feet must be in full contact with the roof. Be
sure that there is no less than 1/2” clearance between the roof and the lightbar
at their closest point. When the mounting feet are in their proper position, lightly

tighten the mounting foot allen head set
screws.

7. Return the lightbar to an upside-down
position. Slide each tinnerman plate
outwards until it is fully engaged with its
corresponding mounting foot. With the
mounting feet and tinnerman plates in their
proper positions firmly tighten all of the set
screws (2 or 4 per side). Flip the lightbar
right side-up and return it to its mounting
position.
