A flasher is a flashing device used to indicate changes in the direction of a car's travel. The flasher is designed with a new type of circuit, consisting of a low voltage switch circuit, a high voltage switch circuit, a pulse generator circuit, a bipolar amplifier dual transistor output circuit, and two sets of light indicator circuits. Install it in the flasher box, and through its control, it can accurately indicate the direction of car travel, especially with the feature of automatic protection. In the event of a short circuit fault in the circuit, it can automatically stop the flasher and light bulb operation. The driver can visually see the working status of the flasher through the fault indicator installed on the flasher, and can detect and troubleshoot faults at any time. There are three common types of flashers: capacitor type, wing type, and transistor type
