ABSTRACT:
A signaling lamp flasher generates audible sound while controlling intermittent contact between a vehicle power source and a signaling lamp. A flash control device generates the intermittent contact, and is preferably an input relay disposed between the power source and the signaling lamp. An IC-based audible flash circuit generates a control pulse in response to the voltage pulse from the power source, generates a buzzer pulse in response to the control pulse, and generates audible sound in response to the buzzer pulse. The signaling lamp flasher also provides current overload protection at the signaling lamp through a pop-out resettable fuse. The location and ability of the fuse to be reset provides improved dependability and serviceability.
