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!

Flange Mount:

Make sure the lighthead will not interfere with existing equipment and be
aware of any items on the opposite side of the mounting surface.

1. Position the flange against
the proposed mounting
location and then, (using a
scribe or similar tool), mark off
the 3 mounting holes. Also
mark off an area in the center
where the 1” wire passage
hole will be drilled.

IMPORTANT: Always check all
measurements before drilling.

2. Using a drill bit sized for a #8
sheet metal screw (and the thickness of the mounting surface) drill
the 3 mounting holes.

3. Drill a 1” dia. wire passage
hole in the area marked.
Be sure to install a
grommet (customer
supplied) into this hole.
Using appropriately sized
wires (minimum 18 AWG),
extend the lighthead wires
to their designations. Fuse
the +12VDC connections at
3 Amps and test the
lighthead, then secure it to
the vehicle with the
supplied mounting
hardware.

Grommet Mount:

Make sure the lighthead will not interfere with existing equipment and be
aware of any items on the opposite side of the mounting surface.

1. Mark the center of the
mounting location onto the
mounting surface. Scribe a
circle onto the mounting
surface using this point as the
center. Refer to the grommet
mounting hole chart for the
proper diameter.

2. Cut the grommet hole out and deburr it.

3. Using appropriately sized wires (Minimum 18 AWG), extend the
lighthead wires to their designations. Fuse the +12VDC connections
at 3 Amps and test the lighthead before securing it to the vehicle.

4. Insert the lighthead into the grommet then secure it to the vehicle by
snapping the grommet into the mounting hole as shown above.

Scan-Lock™ Operation (Brake/Tail/Turn Only):

To cycle through all patterns: Apply Positive (+) voltage to the WHITE­VIOLET wire for less than 1 second and release to cycle forward. Apply
Positive (+) voltage for more than 1 second and release to cycle
backward.

To set a pattern as default: When the desired pattern is displayed, allow
it to run for more than 5 seconds. The beacon will now display this pattern
when activated.

To reset to the factory default pattern: Turn off power. Now, while
applying Positive (+) voltage to the WHITE-VIOLET wire, turn power back
on.

GROUND

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.

NOTE: All customer supplied wires must be sized to
supply at least 125% of the maximum operating
current and be sized at the battery to carry the load.
