Automobile Steering Flasher (6)
When S is put on L or R , +12V voltage will be put on V2. The other circuit will charge C by VD and R1. When C's voltage reaches a certain value, V1 and V2 will be connected. The left turn lamp HL1 or right turn lamp HL2 will be illuminated. After V2 is connected, C will be discharged by V2,VD. V1,V2 will be connected. HL1, HL2 will be off. Then C will be charged by R1 which will make V1,V2 connected. The circuit keeps on working like this.
