The invention discloses a light beam excitation boost filtering type high-power automobile lamp alarm system which is mainly composed of a loudspeaker HA, a control circuit, a triggering circuit, a light-sensitive resistor RL and a capacitance multiple circuit. A light beam excitation type logic amplifying circuit and a boosting filtering circuit which are arranged in series are connected between the light-sensitive resistor RL and the control circuit in series. By means of the light beam excitation boost filtering type high-power automobile lamp alarm system, voltage in the circuits can be boosted, clutter can be filtered out, accuracy of products is further improved, the application range is further widened, an alarm can be automatically given when a driver forgets to turn off automobile lamps, and therefore the situation that a vehicle-mounted storage battery is used up can be effectively eradicated, and the service life of automobile bulbs and the storage battery is prolonged to the maximum extent.
