The invention discloses a steering lamp abnormity feedback circuit and an automobile, the steering lamp abnormity feedback circuit comprises a Fault interface, a first triode Q1, a FeedBack interface, a first resistor R1 and a BCM resistor R01, the Fault interface is connected with the output end of a single-chip microcomputer, and the FeedBack interface is connected with an automobile body controller; wherein the base electrode of the first triode Q1 is connected with the Fault interface, the collector electrode of the first triode Q1 is connected with the FeedBack interface, the emitter electrode of the first triode Q1 is connected with the first resistor R1, the first resistor R1 is connected with the Fault interface and grounded, and the two ends of the BCM resistor R01 are connected with the Fault interface and the automobile body controller respectively. The method has the beneficial effects that the abnormal fault of the steering lamp can be effectively judged and fed back, so that a driver can quickly
