1. A lighting system comprising:
a driver integrated circuit configured to output a DC voltage;
at least one LED circuit having at least two LEDs,
wherein the at least one LED circuit is electrically configured so that a first LED in the at least one LED circuit is electrically connected to and forward biased by the driver integrated circuit and a second LED in the at least one LED circuit is electrically connected to and reverse biased by the driver integrated circuit; and
a switching circuit configured to switch a biasing of the first LED and the second LED in the at least one LED circuit after receiving a signal from a sensor.
