What lights are referred to as headlights?

Turning on the headlights refers to the high beam, low beam, and turn signals of a car. Headlights: Also known as front headlights, they are installed on both sides of the front of the car and are used for illuminating the road during nighttime driving. They can be categorized into two-lamp and four-lamp systems. The illumination effect of headlights can directly affect nighttime driving operations and traffic safety. High beam: The intensity of the light is adjusted based on the distance of the filament. The high beam is focused, emitting light that travels parallel and is more concentrated, with greater brightness, allowing it to illuminate distant and high objects. Low beam: Beyond its focal point (between 1x and 2x the focal distance), the emitted light diverges, illuminating a larger area of nearby objects. Turn signal: An important indicator light that is activated when a vehicle is turning to alert surrounding vehicles and pedestrians. The turn signal uses a xenon tube and is controlled by a microcontroller circuit, operating in an alternating left-right flash pattern continuously.
I remember that turning on the headlights refers to activating the large front lights of the car, specifically designed to illuminate the road, which is particularly important at night or during rainy weather. From my years of driving experience, the control is usually located on the left or right stalk near the steering wheel—just twist or pull the switch to activate the headlights. A blue or green indicator light on the dashboard will then confirm they're on. Using headlights not only enhances driving safety by helping avoid collisions with roadside obstacles or pedestrians but also makes your vehicle's position clear to other drivers. I always prefer turning them on before sunset—developing this habit can help reduce accidents. If you forget, some cars come with an automatic reminder feature, which is quite handy.
