Abstract

An alarming device alarm capable of informing that the signal lamp of the automobile fails down and providing a temporary signal lamp is characterized in that the signal lamp of the automobile is connected with a current detection resistance in series and then connected into the original signal lamp circuit of the automobile; two lamps or a plurality of lamps are separated from each other by LED. One end of the signal lamp connected with a resistance is connected with a base of a triode VT1. The triode VT1 and triode VT2 form an amplifying circuit to drive a relay to work. The relay controls an alarm circuit and the temporary signal lamp. When the signal lamp does not illuminate due to the failure of a light bulb or bad contact when the driver uses the signal lamp, the signal lamp of the automobile does not illuminate and the alarm can effectively remind the driver of repairing the disabled signal lamp instantly and simultaneously a standby signal lamp works.

Description
