Abstract
The utility model discloses a warner for the lamp bulb fault of automobiles, composed of a comparison circuit, an integrated circuit, a stabilizing block, a crystal triode, a light-emitting diode and a sounder. After the voltage of the current of automobile lamp is reduced and divided, the positive input end of a comparison device is input. After the electropositive voltage is divided through a resistance, the electropositive voltage is used as a reference voltage to input one input end of the comparison device simultaneously. After the comparison device compares two voltages, a fixed potential is output to the integrated circuit. Simultaneously a triode is switched on or cut off. When one triode is switched on, a luminous tube emits light. An integrated block inputs high potential. The integrated block also output the high potential. The other triode is switched on. The sounder generates sound. If the automobile lamp is damaged, the sound and the lamp light are achieved to warn simultaneously.
