Lightbar Wiring Instructions
Larger wires and tight connections will provide longer service life for components. For
high current wires it is highly recommended that terminal blocks or soldered connections
be used with shrink tubing to protect the connections. Do not use insulation displace-
ment connectors (e.g. 3M ® Scotchlock type connectors). Route wiring using grommets
and sealant when passing through compartment walls. Minimize the number of splices
to reduce voltage drop. High ambient temperatures (e.g. underhood) will significantly
reduce the current carrying capacity of wires, fuses, and circuit breakers. Use "SXL"
type wire in engine compartment. All wiring should conform to the minimum wire size
and other recommendations of the manufacturer and be protected from moving parts
and hot surfaces. Looms, grommets, cable ties, and similar installation hardware
should be used to anchor and protect all wiring. Fuses or circuit breakers should be
located as close to the power takeoff points as possible and properly sized to protect
the wiring and devices. Particular attention should be paid to the location and method
of making electrical connections and splices to protect these points from corrosion and
loss of conductivity. Ground terminations should only be made to substantial chassis
components, preferably directly to the vehicle battery. The user should install a fuse
sized to approximately 125% of the maximum Amp capacity in the supply line to protect
against short circuits. For example, a 30 Amp fuse should carry a maximum of 24 Amps.
DO NOT USE 1/4" DIAMETER GLASS FUSES AS THEY ARE NOT SUITABLE FOR
CONTINUOUS DUTY IN SIZES ABOVE 15 AMPS. Circuit breakers are very sensitive
to high temperatures and will "false trip" when mounted in hot environments or operated
close to their capacity.
Route the wiring cables into the engine or passenger compartment, taking care to use grommets and to
apply sealant around openings to keep water out. It is advisable to leave an extra loop of cable when
installing the light bar to allow for future changes or reinstallations. Connect the black lead to a solid
frame ground (earth), preferably, the (-) or ground (earth) side of the battery, and the red power wire to
the +12V terminal of the battery through an appropriately rated fuse ( see the fusing considerations sec-
tion for fuse selection ) or breaker. If there is a white wire in the cable, it is not used.
LED Fusing Considerations
Although the average current draw per LED module is very low, the instantaneous peak current to a mod-
ule can be higher during low voltage conditions. To avoid prematurely blowing of ATO style fuses or tripping
breakers it is recommended the following rule-of-thumb be used to size fuses or breakers. This is espe-
cially important in light bars with many LED modules running off a single fused source.
Maintenance
Lens Cleaning
Use plain water and a soft cloth, or Code 3 lens polish and a very soft paper towel or facial tissue. Because
plastic scratches easily, cleaning is recommended only when necessary (about every six months). Do not
subject the lenses to car washes that use brushes, as these will scratch the lenses.
Minimum fuse size calculation:
1.5 x (number of modules being fused)
Example:
LED Duo Beam
TM
Light bar with 4 LED modules .
Minimum fuse requirement for single fuse - 1.5 (4) = 6A minimum
This Product contains high intensity LED devices. To prevent eye damage,
DO NOT stare into light beam at close range.
