[0037] The two output terminals of the left and right turn switch 6 are connected to the two input terminals of the flash relay 3, and are connected in parallel with the double flash control module 2;

[0038] The left and right turn switches 6 are used to activate the circuit for the left turn signal flashing or the right turn signal flashing mode, forming a single output signal and transmitting it to the flashing relay 3, which controls the flashing of the left turn signal group 4 or the right turn signal group 5.

[0039] The double flash control module 2 is used for turning on the double flash mode circuit, converting the single output signal output by the danger alarm switch 1 into a double output signal, and transmitting the double output signal to the flash relay 3, and the flash relay 3 controls the simultaneous flashing of the left turn lamp group 4 and the right turn lamp group 5.

[0040] The flash relay 3 is used for controlling the simultaneous flashing of the left turn lamp group 4 and the right turn lamp group 5 in the double flash mode, and is also used for controlling the flashing of the left turn lamp group 4 or the right turn lamp group 5 in the left turn lamp flashing mode or the right turn lamp flashing mode.

[0041] In some embodiments of the present application, the hard-wired double flash and turn circuit further comprises an alarm module 8, the alarm module 8 is connected in series with the danger alarm switch 1, the alarm module 8 is a complete alarm circuit module, and when the double flash mode circuit is a pass, the alarm module 8 is a pass, and an alarm sound is emitted, the alarm module 8 can adopt a circuit module with an alarm function which is well known in the technical field, and the present embodiment will not be described here.
