What is the small light below the car headlight called?

[StJanelle]

The small light below the car headlight is called a fog light. Here are specific details about fog lights: Types: In addition to the front high beams, low beams, headlights, and small lights, and the rear running lights and brake lights, most cars also have a set of fog lights installed in inconspicuous locations at the rear. Rear fog lights are red signal lights installed at the rear of the vehicle to make it easier for other road traffic participants to spot the vehicle in low-visibility conditions such as fog, snow, rain, or dust. These lights have a higher luminous intensity than tail lights. Position: Fog lights are installed at the front of the car, slightly lower than the headlights, and are used to illuminate the road during rainy or foggy weather. Because visibility is low in foggy conditions, the driver's line of sight is limited. The lights can increase the visible distance, especially yellow fog lights, which have strong light penetration. They enhance the visibility for both the driver and other traffic participants, allowing approaching vehicles and pedestrians to spot each other from a greater distance.
