Beschreibung
Zusammenfassung:	The invention discloses a flash unit. The flash unit comprises a main control module, a plurality of switch acquisition modules and a plurality of driving modules. Each driving module comprises a first field effect transistor and a reverse electromotive force prevention module; the main control module is connected with the power supply; one end of each switch acquisition module is connected with the steering lamp switch, and the other end of each switch acquisition module is connected with the main control module; the grid electrode of the first field-effect tube is connected with the main control module, the source electrode of the first field-effect tube is connected with the steering lamp, and the drain electrode of the first field-effect tube is connected with the power supply; the main control module is used for controlling the first field-effect tube of the corresponding driving module to be switched on after the switch acquisition module acquires the switching-on signal of the steering lamp switch; and
