Safety Information for Installation or Service
•To properly install or service this equipment, you must have a good understanding of automotive mechanical and
electrical procedures and systems, along with proficiency in the installation and service of safety warning equipment.
Always refer to the vehicle’s service manuals when performing equipment installations on a vehicle.
•To be an effective warning device, this product produces bright light that can be hazardous to your eyesight when
viewed at a close range. Do not stare directly into this lighting product at a close range, or permanent damage to
your eyesight may occur.
•Do not install the light system in an area that would block, impair, or blind the driver’s vision. Ensure that the light
system is mounted in a position that is outside the driver’s field of vision so the driver can safely operate the vehicle.
•A light system is a high current system. For the system to function properly, a separate negative (–) connection and
positive (+) connection must be made. All negative connections should be connected to the negative battery
terminal, and a suitable fuse should be installed on the positive battery terminal connection as close to the battery as
possible. Ensure that all wires and fuses are rated correctly to handle the device and system amperage
requirements.
•Never attempt to install aftermarket equipment that connects to the vehicle wiring without reviewing a vehicle wiring
diagram available from the vehicle manufacturer. Ensure that your installation will not affect vehicle operation or
mandated safety functions or circuits. Always check the vehicle for proper operation after installation.
•The lighting system components, especially the outer housing, get hot during operation. Be sure to disconnect power
to the system and allow the system to cool down before handling any components of the system.
•Do not mount a radio antenna within 18 inches (45.7 cm) of the lighting system. Placing the antenna too close to
the lighting system could cause the lighting system to malfunction or be damaged by strong radio fields. Mounting
the antenna too close to the lighting system may also cause the radio noise emitted from the lighting system to
interfere with the reception of the radio transmitter and reduce radio reception.
•Do not attempt to wash any unsealed electrical device while it is connected to its power source.
•DO NOT connect this system to the vehicle battery until ALL other electrical connections are made, mounting of
all components is complete, and you have verified that no shorts exist. If the wiring is shorted to the vehicle body or
frame, high current conductors can cause hazardous sparks, resulting in electrical fires or flying molten metal.
•DO NOT install equipment or route wiring (or the plug-in cord) in the deployment path of an airbag.
•Before drilling into a vehicle structure, ensure that both sides of the surface are clear of anything that could be
damaged. Remove all burrs from drilled holes. To prevent electrical shorts, grommet all drilled holes through which
wiring passes. Also, ensure that the mounting screws do not cause electrical or mechanical damage to the vehicle.

Installation
Attaching the Mounting Flange
The mounting flange shipped with the unit is removable. You can either leave it attached the search light before
installation or attach the flange to the vehicle first. If desired, permanently lock the flange to the base using the three #8
screws provided. See Figure 1.
Figure 1: Search light mounted on flange
DO NOT DRIVE WITHOUT FIRST MOUNTING THE SEARCH LIGHT TO
THE FLANGE: Because vehicle roof construction and driving
conditions vary, do not drive a vehicle if the search light is not
attached to the flange. The light could fly off the vehicle, causing
injury or damage. Repair of damage incurred because of ignoring this
warning shall be the sole responsibility of the user.
To attach the mounting flange:
1. Locate the detent on the search light and one of the two detent
notches on the flange.
2. Align the search light as shown in Figure 1.
3. Push the search light down completely and turn clockwise 1/8 turn
until the detent locks in place.
To remove the search light from the flange:
1. Use a flat-tipped screwdriver to push the detent while turning the
search light counterclockwise.
2. Pull up when the detent is free of the notch.
Figure 2: Permanently locking the flange
If desired, permanently lock the flange to the base using the
three #8 screws provided. See Figure 2.
Wiring
REVERSE POLARITY/MISWIRING: To avoid damage to
the light, ensure that the input voltage is the same as the
voltage rating of the light. Ensure that correct polarity is
observed. Also ensure that the unit is properly fused
with a 5 A fuse.
To wire the search light:
1. Determine the required length of wires needed. The
search light is supplied with 6-Inch 20 AWG wires that
can be connected to longer wires if needed. For lengths
up to 15 feet (5 m), use a minimum 18 AWG (1 mm)
wire. For lengths over 15 feet, use a minimum 16 AWG
(1.5 mm) wire.
2. Install a 5 A fuse and fuse holder to the positive (+)
terminal at the voltage source. Connect one side of the
power switch to this fuse. Connect the light’s red wire to
the switched terminal of the switch.
3. Connect the black (–) wire from the search light to a
known good vehicle ground as close to the unit as is
practical.

DRILLING PRECAUTIONS: When drilling holes, check the area you are drilling into to ensure that you do not
damage vehicle components while drilling. All drilled holes should be deburred, and all sharp edges should be
smoothed. All wire routings going through drilled holes should be protected by a grommet or convolute/split
loom tubing.
To permanently mount the search light:
1. Scribe the locations of the three mounting holes on the mounting surface using the desired mounting holes in the
flange or base as a guide. There are two sets of evenly spaced holes 120° apart on the bottom of the search light
itself. Holes for the #8 self-tapping screws are on a 2.75-inch diameter (where the lines intersect the inner circle in
Figure 3). The holes for the #10 self-tapping screws are on a 4-inch diameter (where the lines intersect the middle
circle in Figure 3). The 4-inch pattern is the preferred pattern for permanent mounting. If one of the optional
mounting flanges is to be used, three #10 screws are on a 6.00-inch circle (where the lines intersect the outer circle
in Figure 3).
2. Drill three 0.177-inch diameter holes for the #8 screws, or three 0.201-inch diameter holes for the #10 screws.
3. Scribe a hole for the wires or an installer-supplied bushing at the center of the screw pattern.
4. Drill a suitably sized hole at the scribed position for the bushing and wire routing hole. Otherwise, route the wires
through the drain notch in the optional mounting flange. Leave open space for water to drain.
5. Align the search light over the drilled holes. Route the wires through the wire routing hole. Seal the hole with a
bushing or RTV if entering a watertight compartment.
6. Secure the base to the mounting surface with the selected panhead screws.

Figure 3: Drilling (Not to scale)
Cigarette Plug models:
Some models will include a cigarette plug with integral fuse and power switch. The switch may be used to remove power
from the light. If direct connection to the power source (not using the cigar lighter plug) is desired, a user-supplied inline
fuse holder and five-amp fuse must be installed in the power cord’s ribbed (positive) lead.
For 24V models:
24V models will have a small transformer included, that must be installed inline between the light and power source, to
allow the light to be hooked up to 24V power supply. Rather than wiring the light to the power source, simply wire the
input side of the transformer to the power source instead, then wire the light to the output side of the transformer.

Magnetic Mounting
DO NOT DRIVE WITH MAGNETICALLY-MOUNTED SEARCH LIGHT INSTALLED:
Because vehicle roof construction and driving conditions vary, do not drive a
vehicle with a magnetically-mounted search light installed. The search light could
fly off the vehicle, causing injury or damage. Repair of damage incurred because
of ignoring this warning shall be the sole responsibility of the user.
The holding power of magnetic mounting systems depends on the surface finish, surface flatness, and thickness of the
steel mounting surface. Therefore, to promote proper magnetic mounting:
•Keep the mounting surface and magnets clean, dry, and free of foreign particles that prevent good surface contact.
•Ensure that the mounting surface is flat.
•Do not use a magnetic mounting system on vehicles with vinyl tops.
•To prevent the sliding of the search light on the mounting surface, avoid quick acceleration and hard stops.
Magnetic mounting provides a secure, temporary mounting method for most installations. However, it is not intended for
use on the exterior of a moving vehicle.
To temporarily mount the search light to a vehicle with magnetic mounting:
1. Place the light assembly on a level, steel surface. Ensure that the light is placed to promote maximum coverage and
range of the search light.
2. Insert the plug at the end of the cable assembly into the 12-volt power outlet socket.
3. Turn the power on and off using the power switch on the plug. To show that the power is on, a pilot light turns on.
4. Use the remote to operate the light.
NOTE: The lighter plug has an integral fuse and power switch. The switch may be used to remove power from the light. If
direct connection to the power source (not using the cigar lighter plug) is desired, a user-supplied inline fuse holder and
five-amp fuse must be installed in the power cord’s ribbed (positive) lead.

Cleaning
CRAZING/CRACKING Crazing (fine cracks) of lenses causes reduced effectiveness of the light. Do not use
cleaning agents (which causes crazing) such as strong detergents, solvents, or petroleum products. If crazing
of the lens es does occur, the reliability of light for emergency signaling purposes may be reduced until the
lenses are replaced.
CLEANING the POLYCARBONATE LENSES: To extend the life of this device, periodic cleaning is necessary.
Clean the lens with a mild, non-abrasive, neutral-pH cleaning agent and a soft, clean cloth. Rinse the device
thoroughly to ensure that no cleaning agent residue remains. To avoid water spots, dry the device with a soft
clean cloth. Failure to follow this precaution can cause crazing or cracking of the lens/dome and voids the
warranty claims for the light.
