Are headlights the same as low beams?

Headlights are not just low beams; they include both low beams and high beams. Headlights are the main lights at the front of a vehicle, and their illumination directly affects nighttime driving operations and traffic safety. Automobile headlights generally consist of a light source (bulb), reflector, lens (diffuser), and housing. To ensure safe nighttime driving, headlights should provide bright and uniform illumination ahead, enabling the driver to identify any obstacles on the road at a distance of 100 meters (or more). Headlights should also be equipped with anti-glare devices to prevent dazzling other drivers and causing accidents during nighttime driving. Low beams are designed for close-range illumination, with the primary requirements being a wide coverage area and a short illumination distance. Low beams are typically composed of the lights on both sides of the front of the vehicle. Low beams should be used in the following situations: on roads without central barriers or centerlines; when meeting another vehicle at night, switch to low beams when the oncoming vehicle is within 150 meters; and when driving at night in conditions with no streetlights, poor lighting, or low visibility due to fog, rain, snow, dust, or hail. High beams are used to extend visibility distance or improve visual clarity. Therefore, they are typically used for extended periods only on roads without streetlights or under poor lighting conditions.
When it comes to car lights, I get really excited. Headlights are a general term, which actually includes two modes: low beam and high beam. For example, when you're driving at night on normal city roads, you use the low beam, which illuminates about 30 meters ahead without dazzling oncoming drivers. On the highway, switching to high beam extends your visibility to over a hundred meters. There's also a clear distinction on the dashboard: a blue light indicator means high beam, while green or white indicates low beam. Nowadays, some cars even come with an automatic switching function that adjusts to low beam when detecting oncoming vehicles, making it super convenient.
