MAINTENANCE
Crazing (cracking) of lenses will cause reduced effectiveness of the light. Do not use cleaning agents (which will cause crazing)
such as strong detergents, solvents, or petroleum products. If crazing of lenses does occur, reliability of light for emergency
signalling purposes may be reduced until lenses are replaced.
Ordinary cleaning of the plastic lenses can be accomplished by using mild soap and a soft cloth. Should fi ne scratches or a haze appear on a lens,
they can ordinarily be removed with a non-abrasive, high quality, one-step, automotive paste cleaner/wax and a soft cloth.
!
Larger wires and tight connections will provide longer service life for components. Do not use insulation displacement 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. under-hood) will signifi cantly 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.
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 and each switched
circuit 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. 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.
WARNING
ELECTRICAL CONNECTIONS
The Scene Light is designed to operate on 12VDC.
Two 12-inch long lead wires are supplied for making electrical connections to the Scene Light.
Using 18-gauge (minimum) wire, connect the red (+) lead to the positive power source terminal and the black (–) lead to the negative power source
terminal.
WARNING
! Any electronic device may create or be affected by electromagnetic interference. After installation of any electronic
device, operate all equipment simultaneously to insure that operation is free of interference.
