The fog lamp is a kind of functional indicator light installed in front of and behind the car. It mainly serves to indicate the role of the vehicle. A pair of fog lamps are installed in front of the car. A pair of fog lamps are also installed behind the car. Generally speaking, it is installed in the fog lamp. The fog light in front of the car will be slightly lower than the headlights. The color of the fog lights is bright, to play the most important role. The color is generally yellow or red to achieve the strongest penetration, but many people There will be some errors in the use of fog lamps. The following is a detailed explanation of the role of fog lamps and related common sense.
The color of the front and rear fog lights is really different! The fog lamp is divided into a front fog lamp and a rear fog lamp. The front fog lamp is generally bright yellow, and the rear fog lamp is red. This is mainly to absorb their essence, red and yellow are the most penetrating colors, but red means “no access”, so choose yellow.
Simply put, the fog lamp is to increase the cohesiveness of the light through multiple refractions of the lamp cover. Especially when used under low visibility conditions, it must have sufficient penetrating power. Because of the low visibility in the fog, the driver’s line of sight is limited. The light can increase the running distance, especially the yellow anti-fog light has a strong light penetration, which can improve the visibility of the driver and the surrounding traffic participants, so that the car and the pedestrian can find each other at a distance.
We know that the fog lamp of a car is divided into a front fog lamp and a rear fog lamp. The function of the fog lamp is different from other lights on the car. It is not used for lighting because the fog lamp uses a scattering officer. The light can be seen through any angle. The intensity of the light causes the fog lamp of the car to penetrate the fog very well. The front fog lamp of the car can remind the driver of the car driving in the foggy weather. The function of the rear fog lamp of the car can be
Under the weather conditions such as fog with low visibility, the vehicle condition is clearly known, so as to prevent the driver of the rear vehicle from loading the front car.
However, one thing to be clear is that although the fog lamp is a scatter lamp, it is common sense to only illuminate a small area near the car, but it is not recommended to use the fog lamp under normal conditions, because if there is no fog In the case of use, the intensity of the light is enough to dazzle the driver’s eyes of the opposite car, the effect is second only to the high beam, and fog light is not recommended in case of heavy rain.
When do you use fog lights? Don’t use disdain to tell me that this is easy. Isn’t it rainy or foggy? This common sense is estimated to be known to five-year-olds! The use of fog lights is not only that, but regarding its use, let’s look at the authoritative statement:
When the visibility is between 200m and 500m, the low beam, the width and the taillight must be turned on. The speed should not exceed 80kmh, and the front lane of the same lane must maintain a distance of more than 150m.
When the visibility is 100-200m, the fog light, low beam light, width light and tail light must be turned on. The speed should not exceed 60kmh, and the distance between the front and the front car should be 100m or more.
When the visibility is 50-100m, the fog light, low beam light, width light and tail light should be turned on. The speed should not exceed 40kmh, and the distance from the front car should be more than 50m.
When the visibility is less than 50m, the public security traffic control department will take traffic control measures to close the expressway in partial and full sections in accordance with regulations.
That is to say, only when the visibility is less than 200m, the fog lamp will be used.
In addition, when using the fog lamp, it is necessary to pay attention to some aspects. Only in the correct way of use can the fog lamp function well, and in the daily driving process, many drivers will use the fog due to the wrong use. Lights cause traffic accidents and even cause casualties, and one thing we need to know is that the use of car fog lights is also subject to legal restrictions. Here are some notes on the use of car fog lights.
1. For general automotive fog lamps, their visibility during design
Generally, it is about 100 meters. Therefore, the fog light must be turned on when the visibility is less than 100 meters. Under different conditions, the speed of the car and the distance between the cars are also limited. Under normal conditions, When the visibility is between 100 meters and 200 meters, the fog lights should also be turned on, and the speed of the car is limited to 80 kilometers per hour, and the distance between the cars should be more than 150 meters. When the visibility is between 50 meters and 100 meters, the fog lights must be turned on, and the speed of the car cannot exceed 40 kilometers per hour, and the distance between cars must be more than 50 meters.
2. For the use of fog lights, there may be a lot of people who don’t know, that is, when the visibility is only a few tens of meters, for example, 30 meters, even if you turn on the fog lights, it still has no effect, because this The time has far exceeded the safety distance, although the transportation department will close the road at this time, but it is still necessary for people in other geographical areas to know this knowledge.
3. In addition to being used in foggy weather, fog lights can provide good light penetration in heavy snow and dust conditions, and try to avoid double flashing lights in foggy weather, especially in turning. When it is time, it is easy to cause a traffic accident.
4. Generally, the front fog light is yellow, and the rear fog light is red. The reason is that the red mark means no traffic, which can play a better warning role.
The state has certain regulations on the setting of fog lamps, so that everyone can ensure safety during the driving process. Everyone must also understand the four points mentioned above about fog lamps, only under the correct driving conditions. In order to fully guarantee their own safety.
