Beschreibung
Zusammenfassung:	The utility model provides a dim lightening prevention circuit in an LED (Light Emitting Diode) indicator lamp of an automobile instrument, relating to the technical field of automobile application. The dim lightening prevention circuit in the LED indicator lamp of the automobile instrument provided by the utility is used for solving the problem of dim lightening existing in a warning signal lamp of an automobile. A first diode V1 to an eighth diode V8 and a thirteenth diode V13 to an eighteenth diode V18 of the dim lightening prevention circuit in the LED indicator lamp of the automobile instrument are LED indicator lamps in an indicating circuit of the conventional automobile instrument. According to the dim lightening prevention circuit, the two ends of the LED indicator lamps in the indicating circuit of the conventional automobile instrument are connected with a resistor in parallel. According to the basic principle of the dim lightening prevention circuit in the LED (Light Emitting Diode) indicator lamp
