How many seconds does a turn signal flash once?

[DeMatthew]

Turn signals typically flash at a frequency of around 1Hz, meaning once per second. If the frequency suddenly increases, it may indicate a fault in one of the turn signals or its circuit. Below is some relevant information about turn signals: 1. Function: Turn signals are controlled by electronic devices, but they still use sound to simulate the clicking of a relay. They are activated when a motor vehicle turns to alert the driver that the turn signal is flashing and to notify surrounding vehicles and pedestrians. 2. Types: Turn signals can mainly be divided into three types: resistance wire type, capacitor type, and electronic type. The resistance wire type can further be categorized into thermal wire type (electrothermal) and vane type (bouncing type), while the electronic type can be divided into hybrid type (with contact relays and electronic components) and fully electronic type (without relays).
