The invention discloses a light beam excitation logic protection emitter coupled double-filtering car light alarm system mainly composed of an audio device HA, a control circuit, a trigger circuit, a photosensitive resistor RL, a capacitance multiplication circuit, a double-filtering amplification circuit, a light beam excitation logic amplification circuit, a low-pass adjustable filter circuit, and a logic protection emitter coupled amplification circuit. The car light alarm system may better filter clutter signals in a circuit, amplifies the clutter signals, further improves product accuracy, expands product application range, and may automatically give an alarm when a driver forget to turn off a car light so as to effectively prevent the car storage battery from being completely consumed and prolong the service lives of the car bulbs and the storage battery to the utmost extent.
