How does a 2-pin flasher work?

A 2-pin flasher works by completing a circuit in a rhythmic pattern to control the flashing rate of turn signals in automotive systems. When the turn signal is activated, the flasher interrupts the circuit, causing the lights to turn off momentarily. It then quickly reconnects the circuit, making the lights flash. The two pins connect to the vehicle's electrical system, and the flasher alternates between open and closed circuits at a specific rate. This on-off cycle creates the characteristic flashing effect, visually signaling the driver's intention to turn. In some models, a buzzer is integrated to provide an audible indication synchronized with the flashing, enhancing safety and awareness.
