CAUTION: Make sure the output voltage of the cigarette lighter (12V or 24V) matches the input voltage
of the light. Some vehicles provide 12VDC output while some vehicles provide 24VDC output. Order the
light to be suitable for your vehicle. Connecting a power source of wrong voltage to the light can
damage the light permanently.
AC Adapter
Connect the waterproof connector of a cigarette lighter adapter cable to the power input socket of the
light. Make sure the notch at the connector and the opening of the socket are aligned. Turn the
waterproof locking nut clockwise until the nut is tight. Plug the AC plug of the adapter into an AC outlet
socket. Our certified AC adapter is auto-switched between 100-240 VAC power supplies.
CAUTION: Make sure the output voltage of the AC power adapter matches the input voltage of the
light. Connecting a power source of wrong voltage to the light can damage the light permanently.
DC Power Source Directly
According to your application, you may prefer connecting to a DC power supply such as a portable DC
battery or DC generator. First, cut the waterproof connector off the input cable extruding from the
base of the light. Prepare the wires for direct connection. Make sure your DC power supply is turned off
while connecting the wires. You can consider adding a switch to the DC power source circuit to turn
power to the light on/off easily. Securely connect the exposed RED wire from the pan-tilt to the
positive terminal of the connection cable from your DC power source. Securely connect the exposed
BLACK wire form the pan-tilt to the negative terminal of the connection cable from your DC power
source. Insulate the connections to avoid any electrical shortage. Turn on your DC power source to turn
on the light. CAUTION: This option must be performed by a licensed electrician. Make sure the output
voltage of the DC power source matches the input voltage of the light. Also make sure the polarities of
the connections are positive to positive and negative to negative. Connecting a wrong voltage or wrong
polarity to the light can damage the light permanently.
MOUNTING THE LIGHT
Permanent Mount on a Board
Typical application of this method is permanently mounting the light on the roof of a vehicle, a boat, a
tower, or a building. These searchlights are usually mounted in an upright position for waterproofing
and maximum tolerance to impact forces. If a highly mounted searchlight needs to illuminate the area
below, the light can be mounted upside down with an optional mounting pan. However, the tolerance
to impact forces is reduced when the light is mounted upside down. We DO NOT recommend mounting
these lights upside down due to the weight of the light. The following instructions apply to mounting
the light in the normal upright position. The electrician must plan ahead to prepare the appropriate DC
power supply and its switching to the light before applying this mounting method.
