When mounting your lightbar, please be sure to keep any radio frequency
sensitive equipment at least 20” from the bar and power cable(s). This is
especially critical in lightbars utilizing strobes. Our strobe power supplies
have been designed to limit RFI emissions, but certain very sensitive
equipment may still be affected. Symptoms may include, but are not
limited to, sporadic operation and degraded performance. Star Headlight
& Lantern Co., Inc. cannot assume any responsibility for any radio
frequency induced malfunction or damage to any radios, sirens, lightbars,
or any other equipment mounted within 20” of a strobe lightbar. Any
antennae mounted in the proximity of the lightbar may cause your radio to
suffer the aforementioned results.
PLEASE NOTE: THE DIRECT MOUNT IS THE
STANDARD MOUNT INCLUDED WITH THE LIGHTBAR.
THE HOOK MOUNTS MUST BE USED ON ALL POLICE
AND/OR OTHER EMERGENCY VEHICLES!!!
THE HOOK MOUNTS ARE SOLD SEPARATELY. THEY
ARE NOT INCLUDED WITH EACH LIGHTBAR. THEY
MUST BE ORDERED SEPARATELY. SEE THE
ACCOMPANYING HOOK MOUNT MANUAL FOR A
COMPLETE LIST OF AVAILABLE MOUNTS AND
KNOWN VEHICLE APPLICATIONS.
I
t is the sole responsibility of the owner to ensure the lightbar is
mounted securely. Check your light every time you enter the
vehicle to ensure that it is mounted securely. The manufacturer
assumes no responsibility for the secure mounting of this light.

Mounting Instructions
Please review the separate Mounting Bracket manual that
is also enclosed with your bar for mounting instructions.
Wiring Instructions
All standard lightbar models are designed for 12VDC negative ground vehicles
only. Reverse polarity will cause serious damage to the lightbar and/or vehicle.
Contact the automotive dealer if there are any doubts about the polarity of your vehicle.
Direct Wiring Guide
PLEASE NOTE: If you are using the existing 15-foot cable supplied with the lightbar,
If the wire supplied is too short, Star recommends direct wiring to the terminal block on
the inside of the lightbar, rather than making connections to the end of the wire that is
supplied. This lightbar is designed so that no wire connectors are needed and only a few
common tools are necessary in order to do this. Direct wiring allows the wire connections
to the lightbar to be made in a clean and dry environment, avoiding any problems that may
arise due to weathering on external connections. There is also an increase in voltage loss
with the addition of each connection. Wiring directly inside the lightbar reduces the number
of connections. However, making connections to the wires already provided is an
acceptable alternative, as long as these connections are good electrical connections and
are resistant from weathering effects. For direct wiring into the lightbar, follow the
instructions listed below.
you may skip to the Electrical Connections section on page 4.
1. Determine the number of wires that you will need to run. This can be done by counting
the number of wires coming out of your lightbar.
2. Using the Wire Usage Table on page 10, identify your wires and select appropriate wire
sizes and colors.
3. Locate the end of the lightbar that has
the external wires entering the base of
the lightbar. The black terminal block
(s), which you will be making your
wire terminations to, should also be
located at this same end.
4. Remove the dome lens at this
end of the lightbar:
Step 1 : Loosen the four screws
holding each dome on.
Step 1
Step
2
Step 2 : Lift the dome off of the base,
exposing the interior
components.
Step 3 : When all work is completed,
reverse the steps to reinstall
the dome, taking care that
the gasket is properly
aligned.

(Direct Wiring Guide CONT’D)
5. All of the wires coming from outside of the lightbar are terminated on the same side of
the terminal block and the wires leading to the internal components terminate on the
opposite side of the terminal block. Loosen the screws on the terminal block and
remove only those wires that exit the lightbar through the hole in the base. There
may be “dead” wires from the harness connected to the terminal block inside your
lightbar, but there will be no wires connected to the terminal across from them. These
are extra wires in the harness that are not used. Replacing these wires in your new
harness is not necessary.

From Wire Harness

Remove
6. Run the new external wires up through the wire bushing into the base and into the
terminal block(s). The function of each of the colored wires in the original wiring harness
is listed in the Wire Harness Usage Table on page 1. There should also be a label next
to the terminal block indicating which color wire should be connected to each terminal.
7. Strip each wire 1/4". Connect the external wires to the proper poles of the terminal
block by inserting the stripped portion of the wire under the rising clamp screw and
tightening down the screw. No wire terminals are needed for connecting wires to this
terminal block.
Be sure to check that no strands of wire are loose and shorting to the
adjacent terminal or to the base of the lightbar.
The correct wire size and color listed in the table on page 1 corresponds directly with the
wiring of the lightbar. All switches used should be rated for at least 125% of their rated load.
8. Once your new wire harness has been connected to the lightbar, you may continue to
the Electrical Connections section.

Electrical Connections
All standard lightbar models are designed for 12VDC negative ground vehicles
only. Reverse polarity will cause serious damage to the lightbar and/or vehicle.
Contact the automotive dealer if there are any doubts about the polarity of your vehicle.
RF INTERFERENCE
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.
• For all standard lightbars, 15 feet of cable (usually including a drain wire and a foil shield)
is supplied with the bar. All wires are color coded and sized at the correct gauge. If this
length is not sufficient, it is recommended that the wire harness be completely replaced
with the only connections to be made directly at the terminal block inside the lightbar.
This will reduce the number of wire connections and help prevent any weathering
problems on these connections. Refer to the Direct Wiring Guide on pages 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, all wires connected to the positive terminal of the
battery should be fused at the battery for 125% of their rated load. The load can be
calculated by adding all lamp wattages and dividing by 13. (Load <Amps> = Total
Watts / 13 volts) Do not use 1/4" diameter glass fuses, as they are not suitable for
continuous duty above 20 amps. A table of recommended wire colors and wire sizes is
provided on page 1. If you are unsure of the current draw, please contact our Customer
Service Department.
• TESTING THE LIGHTBAR BEFORE IT IS PROPERLY FUSED & INSTALLED 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 #10 AWG wire and be as short as possible in order
to minimize the voltage loss in this wire and reduce any chance of overheating.
• Since many of the lightbars we build have custom components, occasionally wire colors
may slightly vary. If you are unsure of the function of a particular wire, you may test the
function by grounding the black wire and applying +12VDC to the wire in question. Be
sure to use a 20-amp fuse when testing.
