Now many cars have cancelled fog lights. What kind of lights are used in foggy days?

Why do many cars cancel fog lights now? This article gives the answer, do you agree?

This configuration of fog lamps is still necessary. Generally, in rainy and foggy weather, fog lights are much better than far and near lights. Many people like to turn on the high beam in rainy and foggy weather, thinking that it is no different from fog lights. Actually, they are not. The high beam is only stronger, and the penetration is definitely not as good as the fog light, because the fog light is yellow. Moreover, the state stipulates that rear fog lamps must be installed. If you cancel the fog lights, there is only one reason: save costs! Besides, there is no other reason!

It is precisely because only the rear fog lights are mandatory and there is no front fog lights, which also gives many car companies an opportunity. However, with the development of science and technology, some models that seem to have no fog lights actually incorporate fog lights into the headlight combination, which is not a reduction. However, at present, this situation basically only appears in high-end luxury models, and some ordinary brand models are nakedly reduced with front fog lights.

However, friends with front fog lights should not turn them on unless necessary, because turning on fog lights during the day will cause considerable interference to the target vehicle, because turning on fog lights during the day is no different from turning on high beam lights. Affect the line of sight of other vehicles, thus causing danger. However, a new technology has come out, that is, laser fog lights, but it has not been popularized.

Whether and how to install fog lights. Let's look at the national standard first, which defines the minimum standards for mass production and sales of automobiles.

According to GB4785-2007 "Specification for Installation of Exterior Lighting and Light Signaling Devices for Cars and Trailers" (4.3. 13~4.3. 14), it is pointed out that:

1. The front fog lamp is optional, and the trailer is prohibited;

2. The number of rear fog lamps must be 1 or 2. There are no special requirements for layout.

At present, the front fog lights of many new models will only be assembled on high-profile models, but not on low-profile models, and some models simply do not have front fog lights. In fact, it is precisely because the national standard does not require this, and naturally it can be saved. However, although the front fog lights are cancelled, the rear fog lights are definitely available. Only some have two, and some have only 1.

However, because it is easy to be confused with the brake lights, if two rear fog lights are equipped, the distance between the rear fog lights and the brake lights must be greater than 10cm, which will greatly affect the size and layout of the lights, so most models still choose only one rear fog light as usual (one is not needed).

Know what it is and why. Why is the national standard so loose for front fog lights? You know, fog lights are very useful in foggy days (halogen light sources have strong penetration).

The reasons can basically be summarized as follows:

1. Fog lights are used to warn other vehicles in rainy and foggy weather. Although daytime running lights (especially LED lights) can not completely replace fog lights, they are widely used and can play a warning role in bad weather.

I remember that when Xinyinglang cancelled the fog lights earlier, the engineers specially answered this question, which probably meant that their daytime running lights were already very bright, so there was no need to add fog lights. The function is largely replaced, and because integrated headlights have gradually become a trend, fog lamps are naturally excluded;

2. Especially fog lights, you can't turn them on at will. If this light is turned on under normal driving conditions, it may lead to blind spots in the oncoming driver's sight or irritate his eyes. To this end, Australia recently increased traffic regulations, and the wrong use of fog lights in cars will be fined 50 to 230 Australian dollars.

One Australian dollar is equivalent to RMB 4.85, and this punishment can be imagined. In China, if fog lights are not used in urban areas, 50 yuan will be fined and 1 minute will be deducted, which is not small.

3. Fog lamps are generally located at the lower bumper, so canceling fog lamps can make more complicated shapes, and making brake vents can also help improve the braking performance of vehicles.
