How to turn on the left turn signal?
1 Answers
To activate the left turn signal, simply pull the lever downward. There is a turn signal lever located below the steering wheel in all vehicles, with 'right' at the top and 'left' at the bottom. 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, which alternates left and right in a continuous flashing pattern. The turn signal employs a flasher unit to achieve the blinking effect, which can mainly be categorized into three types: resistance wire type, capacitor type, and electronic type. The resistance wire type can further be divided into hot wire type and vane type, while the electronic type includes hybrid and fully electronic types. For example, the bounce-type flasher operates on the principle of thermal expansion and contraction, using the heat effect of electric current to cause sudden movement of the spring leaf, thereby connecting and disconnecting the contacts to produce the flashing light.
