What Additional Functions Do Car Turn Signals Have?

[StGabriella]

Car turn signals have the function of indicating turns, as well as providing illumination and a means of communication. Below is an introduction to car turn signals: 1. Introduction: Car turn signals are lights that alert pedestrians or vehicles in front of or behind the car when the vehicle is turning. 2. Principle: The lamp uses a xenon tube, controlled by a microcontroller circuit, with left and right alternating flashes working continuously. Flashers are used: According to their structure, they can be divided into three types: resistance wire type, capacitor type, and electronic type. The resistance wire type can be further divided into thermal wire type (electrothermal) and wing type (spring type), while the electronic type can be divided into hybrid type (with contact relay and electronic components) and fully electronic type (without relay). For example, the spring-type flasher uses the principle of thermal effect of current, with thermal expansion and contraction as the driving force, causing the spring plate to produce sudden movements to connect and disconnect the contacts, achieving light flashing.
