The driving module receives multiple groups of pulse signals at the same time, and according to the frequency and pulse width of the pulse signal, it intermittently supplies power to the turn signal module, so that the car lights light up in the form of flowing water, improving the aesthetics of the turn signal when in use.

[0026] In order to improve the warning effect of the car lights, the input end of the driving module is connected to a flashing module, which is used to output a high-frequency intermittent signal to make the turn signal module flash at a high frequency.

[0027] like Figure 2 As shown, the turn signal module includes several light group circuits, and the circuit structures of all light group circuits are exactly the same. The light group circuit includes a light emitting diode L1 connected in series between the TL1 port and the ground, a resistor R64, a light emitting diode L2, a resistor R65, a light emitting diode L3 and a resistor R66 are connected in series between the output end of the light emitting diode L1 and the ground in sequence, the light emitting diode L1 is connected in parallel to the capacitor C22, the light emitting diode L2 is connected in parallel to the capacitor C23, and the light emitting diode L3 is connected in parallel to the capacitor C24.
