The headlights are lights that turn on at night, and the industry calls them "headlights". Headlamps have general lights and high-brightness xenon lamps, so it can be said that xenon lamps are a type of headlamps.
Fog lights are generally behind and behind, smaller than the headlights and mostly yellow. This kind of light is used when it is foggy, rainy or when the sight is not good. Fog lights have strong light penetrating ability, which can make the sight of driving more clear, and also make the front and rear vehicles and pedestrians more aware of the driving situation of the vehicle.
Fog lights are very useful in rain and fog weather, because fog lights have strong penetrability, and can play a good warning role in rain and fog weather with low visibility, which is much better than headlights. Therefore, pay attention to check whether the fog lamp has water or not.
Although both on the Internet and traffic police are emphasizing the importance of fog lights in rainy and foggy weather, many car owners are still accustomed to using double flashing lights in heavy rain. In fact, there will be many problems. The double flashing light does not penetrate well in rain and fog with low visibility, and sometimes it has a limited effect. In addition, there are many models where the double flashing light is pressed, the turn signal is not used, so the steering is very dangerous in the case of low visibility. Fog lamps are designed for rainy and foggy weather with low visibility. If there are fog lamps but they are not used, it is too wasteful.
