A car headlight, also known as a headlamp, is a device mounted on the front of a vehicle that provides illumination while driving at night or in low-light conditions. Headlights are typically powered by the vehicle's electrical system and can be controlled by the driver to turn on and off or adjust the intensity of the light. They are an important safety feature for cars, allowing drivers to see the road ahead and be seen by other drivers. They are typically made of glass or plastic, and the bulb inside can be incandescent, halogen, xenon, or LED. Some new cars even have adaptive headlights which adjust the direction of light depending on the steering wheel.

　　Some newer vehicles also feature automatic headlight control systems that turn the headlights on and off based on ambient light levels. Headlights are an important safety feature for cars, allowing drivers to see the road ahead and be seen by other drivers.
