Vehicle headlights are essential components of automobiles that 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 for everyone on the road. Headlights come in various types, including halogen, LED, and Xenon, each offering different levels of brightness and energy efficiency. Most vehicles are equipped with two headlights, one on each side of the front. They can be adjusted to different angles and brightness levels, allowing drivers to switch between low beam and high beam settings. Properly functioning headlights are crucial for safe driving and are often checked during vehicle inspections.
