Automotive storage battery charging indication alarm circuit based on LED

The utility model belongs to the technical field of light-emitting diode (LED) application and relates to an automotive storage battery charging indication alarm circuit based on an LED. According to the automotive storage battery charging indication alarm circuit, the problem that a lamp bulb is replaced by the LED in the alarm circuit of an automotive combination instrument to cause insufficient current of the alarm circuit is solved. The light-emitting diode PL1 is in serial connection with a resistor R2 and then in parallel connection with a plurality of resistors and finally in serial connection with a diode RD1, and a cathode of the diode RD1 can serve as an external port of the alarm circuit. The automotive storage battery charging indication alarm circuit is mainly applied to the field of automotive storage battery charging indication alarm circuits.
