It sits inside the lighting circuit where electrical signals from the switch meet the headlight assemblies. It manages the flow of voltage sent to the LEDs so the lights illuminate consistently each time the driver activates them. This electronic control keeps the headlamp system responding smoothly as lighting conditions change on the road. Long after the driver flips the switch, the Mack 84735466 continues directing electrical signals so the LED headlights deliver steady illumination through the vehicle lighting system.
