(Wire Connections CONT’D)
For the RED w/GREEN (Pattern Select) wire, see the LED Flash Pattern Selection section
on page 8.
For the GREEN w/YELLOW (Front Takedowns) and GREEN w/WHITE (Rear Worklights)
wires see the Takedown, Worklight, or Traffic Director Head Programming section on
page 8.
The PURPLE wire is used if you need the ability to switch your lightbar to low power at
night. Leave this wire disconnected to run on constant high power. Connect it to ground
through a switch to allow switching to low power (low when purple connected to ground).
Note: The low power setting decreases the light output of emergency warning lights,
thus reducing their effectiveness. Star does not recommend the use of low power
mode in brightly lit areas (including daylight). Lightbars running on low power may
not comply with applicable emergency warning light standards and/or specifications.
Power Wire Harness
The second harness will contain a red Power wire, a Black Ground wire, and a drain wire.
• Connect the black wire and the drain wire to the negative side of the battery.
• Connect the red wire to the positive terminal of the battery through a fuse at the battery
for 125% of the rated load of all your components. The current for each component is
shown on the Parts list on page 16. Do not use 1/4" diameter glass fuses, as they are
not suitable for continuous duty above 20 amps.
Please Note:
When the red wire is connected to +12VDC the lightbar will draw a small current
(~100 mA). If your vehicle will be sitting for extended periods of time (i.e. more
than a few days), it is recommended the red wire be routed through a switch or
ignition switched relay.
Sample Wiring Connections
The diagram below shows the most common way to hook up a 46” Police lightbar.
Connect your bar in a similar fashion, based upon the wires you will be utilizing in
your Control Harness.
