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!

Installation:
WARNING! The LED models designated “external flasher” must be
connected to an electronic flasher. Allowing the LED to steady burn will
damage the lighthead and void the warranty.
External Flasher Models: 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 WHELEN® sales representative
for specific vehicle application.
Note: Make sure lighthead will not interfere with existing equipment or
any items on the opposite side of the mounting surface.
1. Using the dimensions shown, mark off and drill the four, 1/4” diameter
mounting holes and two, 1” wire holes into the mounting surface. Check
measurements before drilling.
2. Install the four supplied plastic grommets into the mounting holes then
install rubber grommets (customer supplied) into the wire holes.
3. Using appropriately sized wires (minimum wire size - 18 AWG), extend
the lighthead wires to their connections. Fuse the positive connections at
3 Amps and test operation of lighthead before securing it to vehicle.
4. Position the lighthead onto the mounting surface and secure to the
vehicle using the four, #8 x 1-1/2” sheet metal screws.
Flasher Models:
Scan-Lock™: White-Violet Wire / This feature allows the user to
select from several available flash patterns
TO CYCLE THROUGH ALL PATTERNS: Apply positive voltage to the WHITE-
VIOLET wire for less than 1 second and release to cycle forward. Apply
positive voltage to the WHITE-VIOLET wire for more than 1 second and
release to cycle backward.
TO SET A PATTERN AS DEFAULT: Allow the desired pattern to run for more
than 5 seconds. The lighthead will now display this pattern when active.
