Automatic parking light

Automatic parking light
In some countries, it is still obligatory for cars parked in the road at night to have their parking lights on. If the car is parked well before dark, there is an unnecessary drain on the battery. This may be obviated, however, by the present circuit, which ensures that the parking lights do not come on until It gets dark, and are switched off again when it gets light. It has integral delays to prevent the parking lights being switched off by the headlights of passing traffic. The circuit can be enabled only when the ignition is switched off and the parking lights are switched on.
