Abstract

The warning control for the car lights has a transistor switch between the light switch and the ignition switch. This operates a buzzer if the ignition is switched off while the headlights are still switched on, and prevents battery drain. The length of time the buzzer sounds is determined by the size of the capacitor in the base of the switching transistor. This holds the buzzer relay closed for a set time. If the ignition is switched on then the transistor is held in the non switched condition by a line to the ignition circuit.
