Abstract
Status information is provided from an electronic signaling system to an array of N light emitting diodes (LEDs) connected in series between high and low voltage sources, where N≧2, and where N is selected so that the potential difference between the voltage sources is less than the sum of the cut-in voltages of the N LEDs in the array. Control signals are delivered from the electronic signaling system to the LED array over M control lines (N>M≧1), each of which is connected between two of the LEDs in the array. The control signals cause the LEDs to conduct. The control signals are timed so that the LEDs in the array conduct one or two at a time.
