Car headlights are essential components of a vehicle, designed to illuminate the road ahead during low-light conditions, such as at night or in bad weather. They help drivers see obstacles, road signs, and other vehicles, enhancing safety on the road. Headlights typically use halogen, LED, or Xenon bulbs, each offering different levels of brightness and energy efficiency. In addition to providing light, headlights also serve as a signal to other drivers. They can be adjusted to different settings, such as high beams for maximum visibility and low beams to reduce glare for oncoming traffic. Properly functioning headlights are crucial for safe driving.
