A system includes: a light emitting diode (LED); a switching circuit configured to: when in a first state, connect the anode of the LED to a positive potential and connect the cathode of the LED to a ground potential, thereby enabling current flow in a first direction through the LED; and when in a second state, one of: connect the ground potential to the anode of the LED; connect a negative potential to the anode of the LED; and connect the cathode of the LED to the positive potential and connect the anode of the LED to the ground potential, thereby enabling current flow in a second direction through the LED, where the second direction is opposite the first direction; and a driver module configured to selectively transition the switching circuit from the first state to the second state and from the second state to the first state.

A dual mode UV-C disinfection system for the cleaning of automotive cabin air and surfaces includes a UV light source, a motor for moving cabin air in proximity to the at least one UV light source and a shutter configured in proximity to the at least one UV light source. A controller for controlling operation of the light source, motor and shutter and a first sensor for determining the presence of persons within proximity to the at least one UV light source. The UV light source operates to either disinfect cabin air or cabin surfaces depending on the position of the shutter.
