Abstract: A control circuit for turning on/off automobile lights is connected to first, second and third power output units and an input trigger circuit. When a car is started, the second power output unit supplies power to the control circuit. Thereafter, the third power output unit supplies power to the control circuit for each time when the input trigger circuit is conducted electrically.
