The working principle is as follows: the photoelectric isolator U2 is used for integrating the collected signals of the turn signal switch SW into high and low level signals which are input into a P1.1 pin of the singlechip U1. When the driver turns on the turn lamp, the turn lamp switch SW is closed. At this time, the light emitting diode in the optoelectronic isolator U2 is turned on, and at this time, the signal input to the P1.1 pin of the single chip microcomputer U1 is a low potential signal.
