1. Why use lights for rainy days

my country ’s transportation law clearly stipulates:" During the opening period of night street lights，or fog encounters、Rain、Snow、Sand dust、Driving when driving under low visibility of hail，It should be turned on the front light、Surface lights and rear lights。"There are many places to pay attention to when driving on rainy days，Correct use of lights can greatly reduce the chance of encountering an accident。

Do not turn on the lights on rainy days will directly affect the judgment of the rear situation in the front of the car，It is difficult to judge the position of the rear car、distance and speed。If the front seabet logincar is unknown, it will change or steering，It is very likely to cause a rear -end collision accident。We always feel that opening the lights is to let ourselves see the pavement，In fact, I forgot the most important point: opening the lights is not to let you see the pavement, but let others see you better。The following figure can clearly see the difference between opening and non -turning lights。

2. Use different lights in different cases

1. Smaller rainfall should be used

The provisions in the traffic law look broadly，Actually, driving in rainy days is very particular about the use of lights，We should decide what lights are turned on based on the visibility。For example, when it was raining at the beginning of the rain，The sky is dark，But the visibility is not bad，At this time, we should use wide lights。

2. Raiders should turn on headlights or front fog lights

When the rain is relatively large，Rainwater itself will hinder our sight，At the same time, the stagnant water on the pavement will be brought up by the tire rolling in the front car，Form a piece of water mist，It will also have a great impact on sight，At this time, we should turn on the headlight or front fog lamp。Some people think that turning on the fog light will shake to the car in front，In fact, as long as your fog light design is reasonable, this will not occur，Because the fog light itself is not used for lighting when designing，Their beams are very scattered，So it looks bright but not dazzling。

3, heavy rain can turn on a fog light

Only seabet iowhen the rain is very large, the fog lights are turned on，Because our red taillight itself has a very good penetrating power，General heavy rain cannot stop its light，The brightness of the post -fog lights is very high，It is used to penetrate the dense fog，It is easy to shake to the back of the car when used on ordinary rainy days，If the sight of the driver of the car is affected，Then our own safety will not guarantee。

Three, precautions for the use of light on rainy days

1. Do not use double flash during driving

The so -called "double flash" is a dangerous warning lamp，Each car is available，The switch is two sets of triangles together。Domestic abuse of double flash is quite common，In fact, it should only be used in a very dangerous situation，For example, there is an accident ahead，or you need to stop temporarily on the main road。We should not use it during the general driving process，If the abuse of double flash is likely to pass the error message to the surrounding vehicles，Cause danger。

2. Use wide lights for a long time

Demonstration of width light does not let you see the pavement clearly，Instead, let others see you better。During the process of gradually changing the rain，It is obviously incorrect to use wide lights from beginning to end，It should be reasonably switched by lighting according to the rain of rain。
