What is the upward light?

[DiLogan]

Upward is the right turn signal. Definition of turn signal: The turn signal is an important indicator light that is activated when a motor vehicle turns to alert surrounding vehicles and pedestrians. The turn signal tube uses a xenon tube, controlled by a single-chip microcomputer circuit, with alternating left and right flashing for continuous operation. The turn signal employs a flasher to achieve light blinking. It can be mainly divided into three types: resistance wire type, capacitor type, and electronic type. Structure and principle of turn signal: The resistance wire type can be further divided into thermal wire type (electrothermal) and vane type (spring-loaded), while the electronic type can be divided into hybrid type (relay with contacts and electronic components) and fully electronic type (relay-free). For example, the spring-loaded 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 blinking.
