Headlights are essential components of a vehicle, providing illumination for safe driving during low-light conditions, such as at night or in poor weather. Modern headlights come in various technologies, including halogen, LED, and xenon, with LED and xenon offering brighter, more energy-efficient light. They help improve road visibility for drivers and allow other road users to see the vehicle, enhancing overall safety. Additionally, headlights may feature automatic adjustment, fog lights, and adaptive designs for better coverage on the road.
