Is there only one rear fog light?

[Venus]

There is only one rear fog light. The reason for having only one rear fog light is to distinguish it from the brake light, as both the rear fog light and the brake light are red, making it difficult to differentiate them based on color alone, which could affect the judgment of drivers behind. A single rear fog light has higher visibility. The purpose of the rear fog light is to make the vehicle visible to other vehicles in conditions of reduced visibility, such as foggy or rainy weather. Precautions for driving in foggy conditions: 1. Turn on the fog lights, position lights, hazard warning flashers, and low beams to improve visibility and better see vehicles, pedestrians, and road conditions; 2. Try to drive within the lane markings and avoid crossing them; 3. Reduce speed and drive slowly, as poor visibility in foggy conditions can lead to longer stopping distances if the speed is too high; 4. Use the horn to indicate your position and alert other vehicles and pedestrians; 5. Maintain a greater following distance than in normal weather conditions.
