The importance of turning on fog lights in foggy weather is reflected in the following aspects:

1. Improve visibility
The fog lights are designed with low visibility conditions in mind, and can effectively penetrate fog, provide stronger forward lighting, and help drivers see road conditions and obstacles clearly.

2. Increase driving safety
In foggy weather, visibility usually drops to very low. Turning on fog lights can make it easier for other vehicles and pedestrians to see your vehicle, thereby reducing the risk of collision and improving driving safety.

3. Reduce light reflection
The fog lights are positioned low and the light divergence angle is designed reasonably, which helps to reduce the reflection of light in the haze, avoid glare caused by low beam or high beam, and ensure a clearer field of vision.

4. Easy to deal with emergencies
When driving in foggy weather, you can see road changes and potential dangers in time. Turning on fog lights can help drivers react earlier and increase driving safety.

5. Follow traffic regulations
In many areas, turning on fog lights in foggy weather is a legal requirement. Complying with these regulations not only protects yourself, but also maintains the safety of other road users.

6. Improve driving confidence
After turning on the fog lights, the driver's vision will be significantly improved, so that you can drive more confidently in bad weather and improve driving comfort.

In short, turning on the fog lights in time when driving in foggy weather is an important measure to ensure safety and can effectively reduce the risk of accidents.
