Is it necessary to install front fog lights?

[DeHaley]

Vehicles without front fog lights can use headlights as a substitute in foggy conditions, and there is no mandatory requirement to install front fog lights. The following is an extended introduction: 1. Relevant regulations: According to the installation regulations for external lighting and light signaling devices of automobiles and trailers (GB4785), vehicles must be equipped with rear fog lights, but there is no mandatory requirement for the installation of front fog lights. Therefore, some car manufacturers may choose to install front fog lights based on the model and specifications to save costs. 2. Purpose of fog lights: Different models have different configurations, and fog lights are very useful in foggy conditions. Fog lights are installed at the front and rear of the vehicle. Due to low visibility in foggy weather, the driver's line of sight is limited. Fog lights can increase the visibility distance, especially yellow anti-fog lights, which have strong light penetration. They can improve the visibility for the driver and other traffic participants, allowing oncoming vehicles and pedestrians to spot each other from a greater distance.
