Wiring

Main Power Wires

Wiring the TRX lightbar into the vehicles electrical system does not require the use of relays. The power
and ground leads are connected directly to the 12Vdc to 24Vdc supply voltage and are always hot.

 Red to +Vdc
 Black to -Vdc

Control Cable

Activating the Lightbar is done by applying +Vdc to one or more of the lightbar control wires. The control
wires consume only a few milliamps of current and can be used with virtually any on/off switch. There
are five control wires in the Control Cable plus one +Vdc supply feed.

The control wires are color coded and control the functions shown below. Keep in mind that not all
lightbars will be configured in such a way that all control wires are used.

 Orange - Group 1 lamps
 Blue - Group 2 lamps or Second Color lamps
 Brown/White - S.O.S. warning pattern
 Brown wire - Running lamps
 Green wire - Dimming of all lamps
 Red/White - +Vdc

Orange Wire – On single color single beam pattern bars the orange wire will turn on the entire bar. If

the lamps in the lightbar are two beam patterns, half spot and half flood for example, the orange wire
will turn on just the spot lamps.

Blue Wire – If all the lamps in the lightbar have the same beam pattern the blue wire will have no have

no effect on the lightbar and can be ignored. If the lamps in the lightbar are two different beam
patterns, some spot and some flood for example, the blue wire will turn on just the flood lamps. If you
have a multi-beam pattern lightbar and just want on/off functionality simply wire both the orange and
blue wires to a single switch.

If the lightbar is configured as an amber/white combination bar the orange wire will activate the white
lights and the blue wire will activate the amber lights. In case both the orange and blue wires are
activated at the same time the amber lights will activate and the white lights will shut off.

Brown Wire - If the lightbar is configured as an amber/white combination bar, and the amber lights are

activated, the Brown wire will force one lamp to remain white to serve as the required front facing
white light.

Brown/White Wire –Activates the S.O.S. or warning patterns. See below for available flash patterns.

Green Wire – In all lightbars the green wire activates a low intensity or dim setting.

Red/White Wire – In all lightbars the red/white wire is a +Vdc feed that can be used to power one or

more switches.

Changing Patterns and Rates:

To Enter Programming Mode:

1) All Inputs Open, apply Power and ground to the lightbar.

2) Green wire connected to +V.

3) Wait at least one second, Double Tap the Brown wire to +V. All the lamps should flash 3 times to
indicate you've entered Programming Mode.

Note: The Double Tap of the Brown wire must occur within 4 seconds of connecting the Green wire to
+V, otherwise the lightbar will NOT enter Program Mode and will operate normally.

To change the Flash Pattern:

1) Brown/White wire must be Open, i.e. not connected to +V.

2) Tap the Brown wire to +V to step forward through the patterns.

3) Tap the Brown wire to +V twice to step backward through the patterns.

4) Tap and Hold the Brown wire to +V for 3 seconds to reset the pattern to the default flash pattern.

To change the Flash Rate:

1) Connect the Brown/White wire to +V.

2) Tap the Brown wire to +V to step forward through the flash rates.

3) Tap the Brown wire to +V twice to step backward through the flash rates.

4) Tap and Hold the Brown wire to +V for 3 seconds to reset the pattern to the default flash rate.
