Why Do Both Left and Right Turn Signals Light Up Simultaneously?
1 Answers
Turn signal system consists of a flasher relay (referred to as flasher), turn signal switch, turn signal lights, and turn signal indicators. When the hazard warning signal switch is activated, all turn signal lights flash simultaneously, indicating that the vehicle is in an emergency situation and requesting other vehicles to yield. Here are the relevant details: 1. Flash Frequency: The flashing of turn signals is controlled by the flasher relay through current interruption, with a specified flash frequency of 1.5Hz ± 0.5Hz. Some vehicles share the turn signal flasher and hazard warning flasher, while others have them set up separately. 2. Working Principle of Turn Signals: Flashers are used, which can be categorized into three types based on their structure: 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 bounce), while the electronic type can be divided into hybrid type (relay with contacts and electronic components) and fully electronic type (without relay). For example, the spring bounce flasher utilizes the principle of current thermal effect, using thermal expansion and contraction as the driving force to cause sudden movement of the spring plate, thereby connecting and disconnecting the contacts to achieve light flashing.
