Which part of the vehicle does this position of the rotary switch control?

This position of the rotary switch controls the fog lights. Here is an introduction to the purpose of fog lights: Fog lights are installed at the front and rear of the vehicle. They are used for road illumination and safety warning when driving in rainy or foggy weather. Classification of fog lights: Fog lights are divided into front fog lights and rear fog lights. Front fog lights are generally yellow, while rear fog lights are red. The symbols for rear fog lights are slightly different from front fog lights - the light lines of the front fog light symbol point downward, while the rear fog light symbol lines are parallel. These symbols are usually located on the instrument control panel inside the vehicle. In foggy weather, front and rear fog lights are typically used together.
After driving for a long time, I've noticed that the rotary switch is usually a setting on the light control knob. For example, turning it to the first position controls the position lights and taillights, keeping the car visible when parked or in low light; turning it to the second position controls the headlights, responsible for illuminating the road at night. The design of this switch for managing the car lights is kept very simple to prevent dangerous situations caused by complex operations. Sometimes, switch sticking or poor contact can affect the lights—I've experienced this myself when the lights failed on a rainy day, and I had to pull over immediately to check the fuses to avoid an accident. For maintenance, it's recommended to clean the switch contacts every quarter to prevent dust buildup. Experienced drivers know that regular light maintenance can extend the switch's lifespan, saving money and ensuring safety.
