Not all vehicles are required to be equipped with fog lights, but rear fog lights are mandatory by law, while front fog lights depend on the vehicle's configuration. Regulations explicitly require that fog lights must be activated when visibility falls below 200 meters, accompanied by speed and distance restrictions. For example, when visibility ranges between 100 and 200 meters, the speed should not exceed 60 km/h, and the following distance must be maintained at over 100 meters. Fog lights are typically installed in low positions beneath the bumper, with front fog lights symmetrically arranged on both sides, whereas rear fog lights are usually positioned on the left side or both sides of the vehicle's rear. Note that any modifications to fog lights must comply with national standards, and professional installation is recommended to ensure compliance. Proper use of fog lights can significantly enhance driving safety in rainy or foggy conditions, but they should be avoided during normal visibility to prevent distracting other drivers.
