This SmartWire kit is the brain of a reverse light setup for Polaris Sportsman 450 and 570 models from 2016 onward, plugging straight into the vehicle's diagnostic CAN port so the controller reads ECU signals and fires your reverse lights the moment the machine is shifted into reverse. No cutting, splicing or dash-mounted switches are needed, and a manual override lets you light things up without leaving park: shift into neutral, hold the brake for two seconds, and the lights stay on until you repeat the procedure.

Note that this is the harness and controller kit only, so you supply your own reverse lights and pair them with the included custom-engineered wiring harnesses and rugged mounting brackets for a factory-fit finish. The whole package weighs 3 lbs and measures 10 × 8 × 3 in.
