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.
• Failure to use specified installation parts and/or hardware will void the product warranty!
• 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 the 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 (this does not include products that use cigar power cords).
• If this product uses a remote device for activation or control, make sure that this device is located in an area
that allows both the vehicle and the device 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:
The L53 beacon is available in Permanent mount, Magnetic mount and mirror
mount. The L53 beacon is designed to be mounted in a normal dome-up position.
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 at the battery to carry that
load. DO NOT USE CIRCUIT BREAKERS WITH THIS PRODUCT!
Permanent mount:
1. Position the beacon in its mounting location (refer to warnings on page 1).
2. Locate the 3 mounting holes on the bottom of the base. Using the base as a
template, mark the location of the these holes onto the mounting surface.
Remove the beacon and make a mark in the center of the beacons mounted
position for a wire passage hole.
3. Using a #16 drill bit, drill the three mounting holes marked in the previous
step. The wire access hole should be drilled using a 3/8” drill bit. Deburr all
holes and install the rubber grommet (supplied) to protect the wires.
4. Position the mounting gasket onto the mounting surface so that the gasket
holes are aligned with the mounting holes.
5. Feed the wires through the wire access hole in the mounting surface.
6. Align base with mounting holes and secure with #10 sheet metal screws.

Magnetic Mount:
Place the beacon on any flat metal surface and plug the cigar cord into the
vehicles cigar lighter. The beacon is controlled with the On/Off cigar cord switch.
IMPORTANT! The use of any magnetically mounted warning beacon on
the outside of a vehicle while in motion is not recommended and is at
the sole discretion and responsibility of the user.
Scan-Lock™
Unscrew and remove the lens from the base. With the beacon active, to cycle
forward through the patterns short the two solder pads (shown below) for less
than 1 second. More than a second causes the beacon to cycle backwards
through the patterns. To reset to the factory default pattern turn off the beacon,
and with the solder pads shorted out, activate the beacon.
IMPORTANT! It is the responsibility of the installation technician to
make sure that the installation and operation of this product will not
interfere with or compromise the operation or efficiency of any vehicle
equipment! Before returning the vehicle to active service, visually
confirm the proper operation of this product, as well as all vehicle
components/equipment.
