What Does the Headlight Symbol Look Like?

The headlight primarily includes low beam and high beam. The low beam symbol is green with the light direction downward, while the high beam symbol is blue with the light direction straight ahead. Many people mistakenly believe that headlights only refer to the low beam, which is not entirely accurate. In fact, car headlights mainly consist of both low beam and high beam. Regarding the use of headlights, the requirements are to provide adequate illumination while avoiding dazzling oncoming drivers. Therefore, the following points should be noted when using headlights: 1. Keep the headlight lens clean, especially during rain or snow, as dirt can reduce headlight performance by up to 50%. Some vehicle models are equipped with headlight wipers and washers. 2. When two vehicles meet at night, both should switch from high beam to low beam when they are 150m apart to ensure driving safety. 3. To maintain optimal headlight performance, the headlight beam should be inspected and adjusted after replacing the headlight or every 10,000 km of driving. 4. Regularly check the bulbs, wiring sockets, and grounding for oxidation or looseness to ensure good contact and reliable grounding. Loose connections may cause current surges when turning on the headlights, leading to filament burnout, while oxidized connections can reduce bulb brightness due to increased voltage drop.
In my long years of driving, the headlight symbol on the car dashboard has always been a simple yet crucial little icon. It usually resembles a simplified bulb or a pattern of beams radiating outward, with a rounded shape and some upward light lines. The color is dark when the lights are off, and it may light up green or blue when turned on to indicate normal operation. When there's an issue, it turns yellow or flashes, signaling a headlight malfunction or that they're not turned on. I remember one late night on the highway when that symbol didn't light up, and I realized the bulb had burned out—nearly causing an accident. So, I've made it a habit to glance at the dashboard during startup to ensure everything is normal. Keeping an eye on this symbol helps prevent accidents, as it directly relates to nighttime driving visibility and safety compliance with regulations. Newer cars might have more complex designs, but the essence remains easy to recognize.
