The invention discloses a power-amplifying automobile lamp warning system based on a constant current circuit. The warning system consists of acoustic equipment HA, a control circuit connected with the acoustic equipment HA, a trigger circuit connected with the control circuit, a light resistor RL connected with the trigger circuit, and a power amplifying circuit connected with the acoustic equipment HA, the control circuit and the trigger circuit. The warning system is characterized in that the constant current circuit is connected in series between the trigger circuit and the power amplifying circuit. The warning system disclosed by the invention can automatically send out alarm when a driver forgets to turn off automobile lamps, so that the phenomenon that a vehicle-mounted storage battery is exhausted can be avoided effectively, and the service life of the automobile lamp and the service life of the storage battery can be furthest prolonged.
