ABSTRACT:
A flasher apparatus for vehicles capable of informing the presence of short-circuit in a direction indicating system and protecting the direction indicating system from burnout. The flasher apparatus receives both a flashing signal for energizing direction indicating lamps and a detection signal indicative of the electric current flowing to said direction indicating lamps. The detection signal is compared with a reference signal so that the short-circuit in the system is detected. Upon detection of the short-circuit, the direction indicating lamps are prevented from being energized to thereby inform the presence of short-circuit and protect the system. The short-circuit detecting operation is disabled for a period of time in which a comparatively large rush current flows to the direction indicating lamps.
