The main lighting device at the front of a car, typically referred to as "headlights" in both technical fields and daily communication, is the most standard term. Its function is to provide road illumination for night driving, and it is installed on both sides of the vehicle's front, with common configurations including two-lamp and four-lamp systems. Headlights include types such as low beams and high beams: low beams are suitable for short-distance urban lighting, while high beams can enhance visibility beyond 100 meters, improving driving safety. Among them, halogen lamps are widely used due to their low cost and simple structure; xenon lamps offer higher brightness and longer lifespan; LED lamps are characterized by low energy consumption and fast response; laser lamps represent cutting-edge technology and provide more precise lighting effects. Regardless of the type, regular inspection and maintenance of headlights are crucial for ensuring night driving safety, such as timely replacement of aging bulbs or cleaning of lamp covers to maintain optimal lighting performance.
