Which light to use when turning at a signalized intersection?
1 Answers
When turning at a signalized intersection, activate the left or right turn signal as appropriate. Below is an introduction to turn signal knowledge: Introduction: Turn signals are important indicator lights that are activated when a motor vehicle turns to alert surrounding vehicles and pedestrians. The turn signal bulb uses a xenon tube, controlled by a single-chip microcomputer circuit, with alternating left-right flashing in continuous operation. The turn signal employs a flasher unit to achieve light blinking, which can be mainly categorized into three types: resistance wire type, capacitor type, and electronic type. Structural Principle: The resistance wire type can be further divided into thermal filament type (electrothermal) and vane type (spring-loaded), while the electronic type can be subdivided into hybrid type (with contact-type relays and electronic components) and fully electronic type (relay-free). For example, the spring-loaded flasher operates on the principle of current thermal effect, using thermal expansion and contraction as the driving force to create sudden movements in the spring blade, thereby connecting and disconnecting contacts to achieve light blinking.
