How to Turn on the Left Turn Signal of a Car?

[Herbert]

To activate the left turn signal of a car, simply pull the lever downward. There is a turn signal lever located below the steering wheel, with the directions being up for right and down for left. The turn signal is a crucial indicator light that is activated when a motor vehicle is turning, alerting surrounding vehicles and pedestrians. The turn signal bulb uses a xenon tube, controlled by a microcontroller circuit, and operates with alternating left and right flashes without interruption. The turn signal employs a flasher to achieve the blinking effect, which can be mainly categorized into three types: resistance wire type, capacitor type, and electronic type. The resistance wire type can further be divided into thermal wire type and vane type, while the electronic type includes hybrid and fully electronic types. For example, the bounce-type flasher utilizes the thermal effect of electric current, using thermal expansion and contraction as the driving force to create sudden movements in the spring leaf, thereby connecting and disconnecting the contacts to achieve the blinking effect.
