This harness supports two 3-wire* SoundOff Signal perimeter lights. At time of writing, this includes the 3-wire versions of 3" and 4" mPower lights.

This harness is typically used for grille lights and truck tailgates. It can connect to any 3-Wire* FasTech connector and offers two JST connectors for lightheads.

  • 4" from the main connector to the branch point

  • 44" from the branch point to each of two perimeter lights

* The FasTech platform for SoundOff Signal 500-Series Control System has adopted the paradigm of data-driven perimeter lighting. This technology has been tested in numerous fleets, though is not officially supported by SoundOff Signal. Please contact us if you need assistance configuring your perimeter lights.
