Review on Nilight 90001R LED Light Bar Rocker Switch Red 5Pin Laser On/Off LED Light 20A/12V 10A/24V Switch Jumper Wires Set by Marcus Britton

If the power jumper wiring for this switch is connected to battery + as advertised, the "power on" LED on the switch will be lit all the time. The circuit diagram shown will only work if power is supplied from a switched auxiliary source and not battery +. A cable marked as going to a light should not go directly to a large load such as a lightbar. The wire labeled "To Light" should go to terminal 85 of the automotive relay. This relay requires a fused battery + power supply, a ground wire and two wires to the lightbar. I run a switched hot and ground wire all the way to the lightbar instead of relying on the bodywork for the ground path.
