ABSTRACT:
A system and method for illuminating a light source, particularly a vehicle light source. The light source receives a voltage signal causing the light source to be illuminated. A triggering circuit detects the voltage signal. If the voltage signal is at or below a predetermined value, then the triggering circuit maintains a switch closed so that the light source continuously receives the voltage signal. If the voltage signal goes above the predetermined value, the triggering circuit opens and closes the switch in a pulsed manner where the voltage signal applied to the light source is on during the pulses and off between the pulses so that the brightness of the light source remains substantially constant.
