The symbol for fog lights consists of three downward-slanting lines with a vertical bar on the left. Vehicles are equipped with fog lights at both the front and rear, which illuminate the road and provide safety warnings to other vehicles during rainy or foggy weather. The symbols for front and rear fog lights are actually quite similar, both featuring three lines with a vertical bar. When the rear fog light is activated, it makes the vehicle more visible to other road users behind, as it is a red signal light with higher luminous intensity compared to the tail lights. The visibility range of fog lights is approximately 100 meters, and when visibility drops below 100 meters, fog lights should be turned on, and the vehicle speed should be reduced. The fog light switch is positioned separately, making it convenient for the driver to operate while driving.

I remember when I first got my driver's license, the fog light symbols really piqued my curiosity. The front fog light symbol on the dashboard is a green wavy line with a diagonal slash, kind of like a raindrop being split in half—it lights up when activated to remind you. The rear fog light features a yellow wavy line with an arrow pointing to the right, indicating it shines backward. When driving, it's important to distinguish these from the headlight symbol, which typically shows a blue-white straight beam icon. Fog lights are specifically designed for foggy conditions or heavy rain, as their light can penetrate mist without reflecting easily. Remember to turn them off when the weather clears to avoid dazzling other drivers. I used to mix up the rear fog light with the reverse light—the latter is a pure white gear-shaped symbol. In short, new drivers will get familiar with these symbols after seeing them a few times. Safety comes first, especially when driving in cities with heavy smog.

I've been driving for over a decade, and the fog light symbols are etched in my memory. The front fog light is a green wave with a slash, while the rear fog light is a yellow ripple with an arrow. They light up on the dashboard when turned on, proving very practical. Once on a long-distance drive in thick fog, the road was blurry without the fog lights, but visibility improved significantly after turning them on. Compared to the blue-white straight light icon of the headlights, the fog lights' wave design emphasizes their ability to cut through fog. I recommend checking them every time before starting the car and turning them on in bad weather—don't wait for an accident. The rear fog light icon resembles a small flag pointing backward, helping to alert following vehicles of your position. Remember to turn them off after use to save power and be considerate. They're also useful in rain or snow, enhancing safety.

In terms of safety, fog light indicators are particularly important. The front fog light is represented by a green wave with a slash, while the rear fog light features a yellow wave with an arrow icon, symbolizing penetrating light. Turn them on during foggy conditions, heavy rain, or sandstorms to enhance visibility and reduce accident risks. If not activated, the indicators remain dim and inactive. Operation is simple—just twist the switch or press the button—but avoid misuse to prevent dazzling other drivers and compromising road safety.

Technically, the fog light symbols originate from industry-standard designs. The front fog light icon features green wavy lines with a short horizontal bar, simulating light penetrating fog. The rear fog light displays yellow wavy lines paired with a small right-pointing arrow, indicating directional illumination. Colors have clear positioning: green represents forward lighting sources, while yellow signifies rearward warning signals. The dashboard display uses LED backlighting, with icon brightness controlled by circuit switches—low voltage may cause unresponsiveness. During use, they are distinctly differentiated from other lighting functions.
