Abstract: Signal Annunciators are presented that emit short tones upon being triggered by an electrical signal. They are intended primarily as automotive turn signal and emergency light operation indicators and are designed to be connected downstream of the turn signal switch. They comprise oscillating circuitry and piezoelectric discs. In each, capacitors are used to cause a decay in the volume of the tone produced. In the first species, a capacitor is placed in series with the oscillating circuitry. When a signal voltage is applied to the circuit, the capacitor begins to charge, passing current to the oscillator and disc, which emits sound. As the capacitor charges, less and less current is passed, creating a brief tone of decaying volume. The same effect is created in the second species by placing a smaller capacitor in series with the bias current input of the amplifier in the oscillating circuit.

Parking lamps may also be energized, if they are off. But preferably not through the flasher.
