Which button is the fog light on a car?

[River]

The fog light on a car is represented by a button with a semi-elliptical shape on the left and three horizontal lines on the right, intersected by a curved line. Below is some knowledge about fog lights. Function of fog lights: They are used in foggy or rainy conditions when visibility is significantly affected by the weather, making the vehicle more noticeable to others. Therefore, fog lights require a light source with strong penetration. Most vehicles use halogen fog lights, while more advanced options include LED fog lights. Classification of fog lights: Fog lights are divided into front fog lights and rear fog lights. Front fog lights are typically bright yellow, while rear fog lights are red. The symbol for the rear fog light is slightly different from the front fog light—the light lines for the front fog light point downward, while those for the rear fog light are parallel. These symbols are usually located on the dashboard inside the car. Due to their high brightness and strong penetration, fog lights do not scatter light due to fog, so proper use can effectively prevent accidents. In foggy conditions, front and rear fog lights are usually used together.
