The invention comprises use of Dynamically Switchable Bypass (DSB) elements (16A) in association with one or more Light Emitting Diodes (LEDs) (10A, 10C, 10D) in arrays for illumination circuits to provide rugged, reliable lighting. The DSBs are not used as circuit protecting devices, but rather as alternative paths for electric current to bypass failed LEDs (10B). The inventive paired DSB/LED elements overcomes the black-out problems of prior series LED illumination systems, making possible the use of robust LEDs in illumination systems where reliability, long life, low power consumption, low heat output, resistance to shock, vibration, and humidity, and self-diagnosis are important.
