What is the symbol for low beam headlights when driving at night?

The symbol for low beam headlights when driving at night is shaped like a lamp, with the emitted light beam pointing diagonally downward to the left. On the dashboard display, the low beam indicator appears in green. Common vehicle lighting usage scenarios are as follows: Low Beam Headlights: Primarily used for short-range illumination, with a limited projection distance of approximately 25-35 meters. They offer a wide illumination angle of about 160 degrees and cause minimal glare to human vision. These are employed during dusk, nighttime, overcast conditions, rain, snow, fog, and other low-visibility weather. Turn Signals: Located on the left-hand stalk near the steering wheel, turn signals are activated by pushing the lever upward for right turns and downward for left turns. Their main purpose is to indicate an impending turn or lane change. Usage scenarios include: vehicle startup, parking, entering/exiting curves, lane changes, U-turns, overtaking, and entering/exiting roundabouts. Brake Lights: Commonly known as "stop lights," brake lights are positioned on both sides at the rear of the vehicle. A key advantage is that they illuminate whenever the brake pedal is depressed, regardless of whether the vehicle's lights are on. This serves to alert following drivers that the vehicle is decelerating, prompting them to adjust speed and maintain a safe following distance.
As a regular driver who often drives at night, I find the low beam symbol quite prominent on the dashboard—it's a small bulb icon tilted downward on the right front, symbolizing the headlights illuminating the road nearby. Turning it on is straightforward: just rotate the light control stalk near the steering wheel to the low beam position. Once activated, the icon lights up in green or blue. It's crucial to distinguish this symbol from the high beam: the high beam icon shows the light beams pointing upward, while the low beam is designed to avoid dazzling other drivers, making it safer in urban areas or heavy traffic. Additionally, in some newer car models, the symbol might have slight variations, like an added downward arrow, but the essence remains similar. If you don't see this symbol illuminated while driving at night, it could mean the lights are off or malfunctioning—check if the bulb is burnt out or if there's poor wiring contact. It's best to develop a habit of verifying the light status upon each startup, combining it with other symbols like the fog light (with a wavy line) to enhance nighttime visibility. Safe driving starts here—don’t overlook these small details.
