In automotive terminology, "blinker" refers to the flashing lights on the exterior of a vehicle used to indicate the intention to turn or change lanes, commonly known as turn signals or direction indicators. These lights, which flash regularly, alert surrounding vehicles and pedestrians to the driver's intended change in direction, and are crucial components for driving safety. Terms like "directional light" or "signal lamp" appear more frequently in technical documents. Modern vehicles typically use LED turn signals, which offer advantages such as fast response, low energy consumption, and long lifespan. Some high-end models are also equipped with an automatic cancellation function, which turns the signals off automatically after the turn is completed. According to regulatory requirements, drivers should activate the turn signal at least 3 seconds before changing lanes or turning to ensure sufficient safety warning time. If the turn signal malfunctions, the fuse or bulb condition should be checked promptly to avoid traffic accidents caused by signal failure.
