Headlights are essential components of vehicles, 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 either halogen, LED, or Xenon bulbs, each offering different levels of brightness and energy efficiency. Modern headlights often come with features like automatic dimming, which adjusts the brightness based on surrounding light, and adaptive lighting, which changes the direction of the beam when turning. These advancements improve visibility and help prevent accidents, making driving safer for everyone.
