Star Headlight & Lantern 7400 Star Lase - Manual (Page 4)

• All standard Mini Laser lightbars have a 15’ harness. It has 10-conductors (plus a drain wire and a
foil shield). All wires are color coded and sized at the correct gauge. If this length is not sufficient,
it is recommended that the wire harnesses be completely replaced, with the only connections to be
made directly at the terminal blocks inside the lightbar. This will reduce the number of wire
connections and help prevent any weathering problems on these connections. Refer to the Wire
Harness Replacement section on the page 3-4 for further instructions on this.
• CAUTION: All wires and switches should be rated for at least 125% of their maximum
current load. In addition, the red power wire should be connected to the positive terminal of the
battery and fused at the battery for 125% of its rated load. The current for each component is
shown on the Parts list on page 7. Do not use a 1/4" diameter glass fuse, as it is not suitable for
continuous duty above 20 amps. If you are unsure of the current draw, please contact our
Customer Service Department.
• TESTING THE LIGHTBAR BEFORE IT IS PROPERLY FUSED WILL VOID THE WARRANTY!!
• The black ground wire should be connected to the negative terminal of your vehicle’s battery. This
wire should be at least #14 AWG wire and be as short as possible in order to minimize the voltage
loss in this wire and reduce any chance of overheating.
• The Wire Connection section and diagram on the next page lists the different wire colors and the
lights controlled by those wires. Your harness WILL contain all 10 of the colored wires, the drain
wire, and a foil shield, although they will not all be utilized.
Please take the following steps to help eliminate any Radio Frequency Interference (RFI) with
your two-way radio.
• DO NOT run the power wire for the lightbar along same path as any antenna wires.
• DO NOT run the power wire for the lightbar along same path as any radio power
wires.
• DO NOT tap power for the lightbar off of the radio power wires.
• DO NOT mount the lightbar within 20” of any antennae. Sometimes mounting the
lightbar or antenna over by just one foot can make a large difference in the
interference.
• Ensure the black wire from the lightbar has a good connection to the negative side of
the battery.

Mounting Instructions
Please review the separate Mounting Bracket manual that
is also enclosed with your bar for mounting instructions.
Wiring Instructions
PLEASE NOTE: If you need a cable longer than the existing 15-foot harnesses
supplied with the lightbar, it is recommended that you completely
replace the harness, rather than adding on to it. Please see the
Wire Harness Replacement section on pages 3-4.
