How to use lights in rainy, snowy and foggy days

In principle, fog lights should be turned on in rainy and snowy weather. The fog lights are turned on in different cars. Generally speaking, it is on the turn signal handle (left side), as shown below.

Turn on the front fog lights, so that the oncoming cars and pedestrians in front can correctly identify the oncoming cars and avoid them safely.

Turn on the rear fog light, so that the rear car can correctly identify the vehicle, thus maintaining an appropriate distance and speed.

Advantages: The fog lamp has strong penetration and high recognition, and the fog lamp hardly produces Tindal effect, so that the light will not hit the fog to block the line of sight, and it can also illuminate the nearby ground. This is also the key to distinguish fog lamps from other lamps. The front fog lights are usually bright yellow and the rear fog lights are red. Red and yellow are the most penetrating colors.

Disadvantages: The device for turning on fog lamps is hidden, and it needs skilled use to turn them on correctly. Moreover, on the way, after turning on the fog light, the driver has no obvious intuitive feeling, and he is not sure whether it has been turned on successfully (although there is a display on the dashboard, whether the light is broken or not is anyone's guess after a long time). Just like many drivers don't know whether the brake lights of their vehicles are on two or only one. )

In reality, many drivers are used to turning on double flashing warning lights in rainy, snowy or foggy weather, which is scientifically called "danger warning flashing". The open button is as follows:

Advantages: People are used to turning on this warning light mainly because it is easy to turn on and easy to find on the control platform. This warning light is in a dynamic flashing state, and the warning effect is obvious.

Disadvantages: whether the double flashing warning light is suitable for rainy and foggy weather is controversial, strictly speaking, it is not applicable. After the double flashing warning light is turned on, the indication function of the turn signal may be affected when turning normally (some models will distinguish between the double flashing warning light and the turn signal, but not all models will distinguish between them. After all, the same light is used, so the rhythm of the flashing light must be adjusted to distinguish).

Tip: In theory, the double flashing warning light is only used to indicate the extreme deviation between the vehicle speed and the regulations, and to remind the vehicle to slow down or even stop. Not suitable for rainy and foggy weather. This is also the reason why many old drivers dislike other vehicles using double flashing lights in rainy and foggy weather.

Therefore, if you use the double flashing warning light for a long time in rainy and foggy weather, please be alert to the old drivers with anger road disease!
