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!

IMPORTANT! The lightbar should be a minimum of 16" from any radio antennas!
Mounting your Lightbar:
This lightbar mounts with 4 bolts affixed to mounting plates that slide into the track on the bottom of the
lighbar base. Figures 1 and 1a show how the slide bolt assembly slides into your lightbars base and mounts
onto the vehicle. Use an appropriately sized drill bit sized for a 1/2 - #13 X 2” bolt, to drill the mounting
holes. When securing the slide bolts to the bottom of the lightbar base, be sure the outside bolts are spaced
far enough apart and near enough to the ends of the vehicle roof.
Lightbar Cables:
This lightbar uses a 3-conductor cable for LEDs, a 6 conductor cable for HALOGEN and a 4-conductor
cable for BRAKE/TAIL lights. Extend the 3- and 6-conductor cables towards your switch panel. The
instructions included with your switches will provide switch wiring information. The 4-conductor cable
connects to your brake light. There are also 2 wires for Scan-Lock™ (flash pattern selection).
Refer to the parts illustration on the next page for wire designations and fusing.
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
that load. DO NOT USE CIRCUIT BREAKERS WITH THIS PRODUCT!
at the battery to carry
Scan-Lock™
In the Scan-Lock™ cable the RED wire controls the front LEDs and the GREEN wire controls the rear
LEDs. The LEDs must be on for flash pattern selection.
TO CHANGE PATTERNS: Apply +12 volts to the Scan-Lock™ wire for less than 1 second and release to
cycle forward to the next available pattern. Apply +12 volts to the the Scan-Lock™ wire for more than 1
second and release to cycle back to the previous pattern.
TO CHANGE THE DEFAULT PATTERN: When the
desired pattern is displayed, allow it to run for more than 5
seconds. The lighthead will now display this pattern when
initially activated.
TO RESTORE THE FACTORY DEFAULT PATTERN:
Apply +12 volts to the Scan-Lock™ wire. With ScanLock™ activated, turn power to the lighthead on. The
factory default pattern will now be displayed.
A normally open momentary switch can be used to control Scan-Lock operation.
IMPORTANT WARNING!
CAUTION! DO NOT LOOK DIRECTLY AT
THESE LEDS WHILE THEY ARE ON.
MOMENTARY BLINDNESS AND/OR EYE
DAMAGE COULD RESULT!
