Wiring Diagram Description
The wiring diagram illustrates the connection of one or two LED light bars to a vehicle's electrical system using a Nilight wiring harness. The harness includes a relay, a fuse, and a rocker switch.
Each light bar has a red wire (positive) and a black wire (negative). These connect to the wiring harness.
The wiring harness then connects to the relay. It also incorporates a fuse holder for protection.
The fuse is connected to the positive terminal of the vehicle's power source (implied). The output of the fuse connects to one terminal of the rocker switch.
The rocker switch controls the activation of the circuit. It is connected to the relay. The diagram indicates a negative connection from the switch to the relay, and a positive connection from the fuse to the switch.
The relay acts as a switch for the high-current circuit powering the light bars, controlled by the low-current signal from the rocker switch and vehicle power.
