A vehicle lighting system includes a rotatable, depressible, rotary dimmer switch with a light emitting diode ring indicator and a vehicle lighting controller. The vehicle lighting controller controls the operation of at least a first lighting circuit and a second lighting circuit. A digital input from the rotary dimmer switch places the controller in a first configuration mode or a second configuration mode. The digital input from the rotary dimmer also switches between apply configuring the first lighting circuit or the second lighting circuit. The LED illuminates in a first color for the first circuit and a second color for the second circuit. The rotary dimmer adjusts the operating parameter and/or the overcurrent protection associated with the first lighting circuit and the second lighting circuit.
