High, low and backlight functions are part of the appeal of an LP Pro light. This 640172 harness brings the correct power and switching arrangement together for up to two compatible lights, with a high/off/low toggle and relay included. It is the straightforward choice when you want a dedicated switched installation for your LP6 Pro or LP9 Pro lights.
SKU: 640172
The on/off/on toggle selects the high or low circuit without powering both together. That separation matters: supplying high and low simultaneously can damage the light. The harness includes the relay, light leads and battery connections, plus a backlight trigger lead.
The harness is 144in long. Plan the route from the battery to the lights and the switch position, keeping the wiring away from heat, sharp edges and moving parts.
The light leads use Deutsch connectors, but the complete installation also includes mounting the relay and switch and connecting the backlight trigger to the running-light circuit. The fitting guide specifies a 1/2in mounting hole for the supplied toggle switch.
If you already use suitable factory upfitter switches or a control module, the 640167 lock-out harness is the alternative to consider. The 640168 controller pigtail is a separate one-per-light wiring component for a custom control installation.

Up to two compatible LP6/LP9 Pro lights. The harness is not a light-pod kit.
Yes. An on/off/on high/low toggle switch is included, along with the relay and harness.
The light leads use Deutsch connectors. You also need to fit the relay and switch, connect battery power and join the backlight trigger to the appropriate running-light circuit.
No. Keep them separated as this harness is designed to do. Powering both at once can damage the lights.
Choose around the control system you want. This is the dedicated switched harness; 640167 is the alternative for integrating suitable existing upfitter or power-module controls.
