90% of the people don't know: Why does your car have no front fog lights?

before writing this article, I would like to talk about the background. Once, the professor attended an event. Some media friends present asked a leader of the event organizer: Why is the car released this time, there is no standard front fog lamp in the whole system? The leader hesitated for a long time, and he replied that we would consider this suggestion and hope to add front fog lamps in future versions.

Professor looked at the configuration of mainstream car brands on the market and found a strange phenomenon, the front fog lights gradually disappeared!

in everyone's thinking, the fog lamp is a safe configuration, and the low configuration is not high. In many car evaluation videos, when it comes to the absence of front fog lamps, the host must pretend to be forced to say: We strongly recommend that manufacturers do not reduce the allocation!

But in fact . . . . . . The professor found that the current car is equipped with low front fog lamps and high front fog lamps . . . . . .

even many high-end cars have no front fog lamps.

Why are cars now slowly giving up front fog lamps? It's not a high-tech configuration.

before explaining the problem, let's take a look at what fog lamps do. Fog lamp belongs to one of the car's signal lights. Its characteristic is its strong penetration. In foggy weather, fog lamp can let others see you, which is very important for driving safety. In our country, according to the national standards GB4660 and GB4785, the rear fog lamps of automobiles must be available, but there is no explanation of how many. All cars have only one fog lamp, and the fog lamps must be on the left. Many car factories may have a fog lamp on the left and a reverse lamp on the right due to cost or design considerations (Then who, delete this sentence if necessary before Publishing).

in our country, visibility is also stipulated at 100- Fog lamps must be turned on within 200, but only on expressways. If used in the city, deduct 1 point fine 50 yuan. However, the installation requirement of front fog lamps is only 'optional', which is a good explanation why some vehicles or models are not equipped with front fog lamps. However, the absence of front fog lamps does not mean that the car factory ignores this safety configuration.

daytime running lights replace front fog lights?

The Professor chose a more representative car model, selling for more than 10 thousand to more than. According to the principle, such a high-end car, front fog lamps have limited impact on cost, but we can see that low-equipped models with daytime running lamps do not have front fog lamps, and high-equipped models with front fog lamps do not have daytime running lamps. The professor checked the configuration of several models. They all have this in common. Cars without front fog lights generally have daytime running lights.

of course, there are also many cars that have neither front fog lamps nor daytime running lights, but the prices of these cars are basically relatively cheap, buying vegetable cars below 100,000, from the perspective of safety, this kind of car must be severely criticized!

then there are two situations now. One is that there is no front fog lamp and no daytime running lamp, one is that other light sources replace independent front fog lamps or are integrated into the headlight assembly.

and this light source is the daytime running lights.

Many people think that the daytime running lamp is just a cooler configuration. In fact, this daytime running lamp has been used for a long time in foreign countries. When it is foggy, its own car is easier to be found by the front car. The daytime running lamp is not a lighting source, but a signal lamp, which seems to be the same as the function of the front fog lamp.

However, there is still a problem with daytime running lights replacing front fog lights, that is, penetration. Needless to say, the penetration of traditional fog lights is definitely better than that of daytime running lights. The color temperature of the front fog lamp is about 3000 K, and the yellow color has strong penetrability; The color temperature of HID and LED lamps ranges from 4200K to over 8000 K; The higher the color temperature of the lamp, the worse the penetration to fog and rain. Therefore, if you pay attention to driving safety, it is best to buy the front fog lamps with daytime running lights.

The traditional fog lights will disappear in the future

although the penetration of LED daytime running lights is poor, many car factories (Or a lamp factory, such as Ma Ruili)Everyone has already thought of a solution. Many car models already have detectors on them, which can monitor moving objects and light sources in front of them, thus controlling the light source and angle of the lights, so that while increasing the driving recognition, it does not affect the driving safety of others.

when driving at night, under normal circumstances, the matrix LED headlamp will use the high beam to illuminate the front, once the light source sensor of the system detects that the emitted light beam hits the opposite side or the vehicle in front, it will automatically adjust or turn off several LED cells in the lamp group, let the front vehicle not be affected by dazzling high brightness LED. The front car can clearly know where you are, and the function of the front fog lamp is replaced.

In addition, there is laser taillight technology. Take Audi as an example. Although fog lamps have strong penetration ability, in extreme weather conditions, the fog lamp beam may still be affected by smog, thus weakening the penetration ability of the beam.

The laser rear fog lamp uses the characteristics of laser beam directional luminescence to improve this problem. The laser beam emitted by the laser fog lamp is fan-shaped and oblique to the ground, which not only plays a role in prompting the rear car, but also avoids the influence of the beam on the rear driver.

at present, it is difficult to find front fog lamps for cars with slightly higher prices. The disappearance of front fog lamps is already the general trend, and it seems that it is not far from being replaced by more intelligent headlights.
