The invention discloses an excitation type low-pass adjustable boost filtering high-power vehicle lamp warning system. The system mainly consists of a sound HA, a control circuit connected with the sound HA, a trigger circuit connected with the control circuit, a photosensitive resistor RL connected with the trigger circuit, and a capacitance multiple circuit connected with the trigger circuit. The system is characterized in that a light beam excitation type logic amplification circuit and a booster filtering circuit, arranged in series, are serially connected between the photosensitive resistor RL and the control circuit; and a low-pass adjustable filtering circuit is serially connected between the light beam excitation type logic amplification circuit and the sound HA. The system can raise voltage in the circuits, can filter noise waves to further improve the product precision and to widen the application range, and can automatically give an alarm when drivers forget to turn off a vehicle lamp, so that the condition of an exhausted vehicle-mounted accumulator can be effectively prevented, and the service life of vehicle bulbs and the accumulator is prolonged to a greatest extent.
