The invention discloses a light beam stimulation type and voltage-rise filtering type automobile lamp turnoff missing alarm. The alarm mainly comprises a sound HA, a control circuit, a photoresistor RL, a voltage-rise filtering circuit and the like, wherein the control circult comprises a triode VT1, a triode VT2, a resistor R1, a resistor R2, a resistor R3 and the like, wherein one end of the resistor R1 is connected with a base of the triode VT1; an automobile engine switch is in an external connection with the other end of the resistor R1; one end of the resistor R2 is connected with a collector of the triode VT1; the other end of the resistor R2 is connected with an automobile lamp switch through a diode array group; one end of the resistor R3 is connected with an emitter of the triode VT1; and the other end of the resistor R3 is connected with a negative electrode of the sound HA. According to the light beam stimulation type and voltage-rise filtering type automobile lamp turnoff missing alarm disclosed by the invention, the voltage in the circuit can be increased and clutters can be also filtered so that the accuracy of the product is improved and the application range of the product is enlarged; and an alarm can be also automatically sent out when a driver forgets to turn off an automobile lamp so that a vehicle battery can be effectively prevented from being exhausted; therefore, service lives of an automobile bulb and a battery are furthest prolonged.
