Why do some cars only have one fog light and one reversing light?

Hello, first of all, we might as well make clear the role of the reversing lights, of course, the reversing lights are installed in the rear of the car, which are used to illuminate the road surface behind the car when reversing, and play a role in warning the vehicles and pedestrians behind the car. However, many car owners have found that their car has only one reversing light, which looks so awkward.

This is actually allowed by national regulations, and the length of the vehicle is less than 6 meters to install 1, and 1 more can be optional. Due to the mandatory installation of one by national regulations, many manufacturers have reduced the configuration of another reversing lamp on the basis of complying with national regulations.

In fact, only a bright car reversing light can attract the driver's attention, and the symmetrical lights will make the driver paralyzed, mistakenly thinking that the car in front is driving in the wrong direction.

In addition, the position of the reversing lights is not random, usually the left fog lights, the right reversing lights. This is because the driver's seat in China is on the left, and the fog lights are on the left, which can better observe the vehicle in front; The reversing light is on the right, which is convenient for the driver to reverse and stop on the right side of the road at night.

If you feel that the reversing vision is poor, then what should the owner do? The first driver can get out of the car to observe the environment behind the vehicle to make sure that there are no obstacles, and then get into the car to operate. The reversing speed should be well controlled, and with the reversing radar or reversing image, the reversing safety will be improved a lot.

Cars, as many families' beloved objects, should have a symmetrical beauty, so why do many cars have a reversing light?

Fog lights are divided into front fog lights and rear fog lights, the front fog lights are not available in every car, and the rear fog lights are available in all cars. But not every car can fit you two. So we can see on the road that some cars have front fog lights, and some don't; All cars have rear fog lights, but some cars are two and some are one.

The reason for this situation is that the manufacturer saves costs. Look

Hello, there are two or three brake lights, one or two reversing lights, thank you.

The rear fog lights and reversing lights each have only one reason for holding the stove.

According to the EU ECE R38 regulation, most EU countries allow: one or two rear fog lights. If only one rear fog lamp is configured, its bit.

The set can be in aThe body is positive**, or bOn the same side as the driver. If two are arranged, they must be symmetrical.

2.However, because the two rear fog lights are indeed easy to be confused with the brake lights, it is stipulated in ECE R48 that if two rear fog lights are configured, the position of the rear fog lights must be more than 10cm away from the brake lights.

I think that's why European automakers only use one rear fog lamp. Because if you want to pull the distance to more than 10cm, it is likely to destroy the overall beauty of the entire taillight group).

3.The brightness of the rear fog lamp is specified in EEC 77 538: within the viewing angle of 10 degrees on the horizontal axis and 5 degrees on the vertical axis, the illuminance is not.

It must be less than 150cd, but not greater than 300cdThe lampshade area of the rear fog lamp should not be greater than 140 square centimeters. The color must be red, and the color temperature must not exceed the CIE standard of 2,854K

4.ECE R38 also stipulates that rear fog lamps can only be turned on when one of the three is on: front fog lamps, high lights, or near lights. And.

It must be possible to manually turn off the rear fog lights separately without turning them off.

5.The dashboard in the car indicates that the rear fog lights are lit on the relative signal, which must be [yellow and anti-ante]. Only vehicles before January 1981 can be used.

with green. 6.Rear fog lamps were first used in Europe in the 1950s and were introduced to the United States in the late 1980s (early 1990s).

7.Regulations in the United States and the European Union: At least one reversing light (so no need to install two).

Trouble, thanks!

There are two front fog lights for the Beijing X7, and both of them are LED light sources. Beijing X7 reversing lights are only one, but different brands of cars have two reversing lights, according to the relevant national laws and regulations at least one reversing lights, of course, it is not excluded that manufacturers in order to save costs and use a reversing lights.

Yes, China's car lighting regulations are based on European car regulations, which stipulate that there must be more than one anti-fog lamp behind the rear, and on the driver's side, because the early sensitivity is symmetrical, the reversing lights can only be installed on the other side, so the X7 reversing lights are on the right side, and the anti-fog lights are on the left side.

Yes, many cars are configured like this now, and the more expensive ones will be equipped with two.

There is only one rear fog light, and there is only one rear fog light The reason is to distinguish the rear fog lights and brake lights, the rear fog lights and brake lights are red, and it is difficult to distinguish them from the color alone, which affects the judgment of the rear car driver, and a rear fog light is highly recognizable. The function of the rear fog lights is to let other vehicles see the car in foggy or rainy days when visibility is greatly affected by the weather. Precautions for driving in foggy weather:

1. Turn on fog lights, marker lights, hazard warning flashing lights and low beams to improve visibility, see vehicles, pedestrians and road conditions; 2. In the fog, try to separate the line and drive the car collapse, do not roll the line; 3. Closing and circulating, slowing down and slowing down in foggy days, due to low visibility, poor line of sight, and too fast speed, the braking distance will be too long; 4. Honk your horn to indicate your location to alert vehicles and pedestrians; 5. Keep a distance away from the car in normal weather.

According to the understanding of many friends do not know much about some of them, in order to facilitate everyone to understand these knowledge, so today I will introduce to you about the reversing lights and fog lights? This question, interested partners can learn about it, and it may be helpful for you. For a long time, reversing lights have basically played a more vital role at night.

Generally, it is basically the next model, and some cars currently only use one. In other words, according to national regulations, a car with a length of less than 6 meters needs to be installed, and one can be optional. Because the national regulations require the installation of one, many car companies have reduced the number of reversing lights on the basis of meeting the national regulations.

In addition to the reversing lights, the situation of the fog lights is somewhat similar. According to national regulations, it is mandatory to install a fog lamp, which can be optional. If only one is installed, it must be on the left side.

Secondly, shortening the backup lights and fog lights is also good for the little partner. Symmetrical lights up and down will cause paralyzing reactions from the driver in the driver's track, and a single light will attract the driver's attention. Two symmetrical reversing lights may make the driver think that the vehicle in front is reversing at night, while a single reversing light will be easier to identify.

Why are the left fog lights and right reversing lights designed this way? Because in China, the left-hand drive is driving, and the fog lights on the left side can give the rear driver a better view of the car in front; The reversing light is on the right, which makes it convenient for the driver to park on the right side of the road at night. It not only complies with national regulations, but also shortens the production cost, so at present, many car companies will basically shorten the cost of reversing lights and fog lights!

According to the EU ECE R38 law, if two rear fog lights are installed at the rear of the vehicle, the position must be more than 10cm away from the brake lights......Since the rear fog lights are red like the width indicator lights and brake lights, the rear fog lights and brake lights are easily confused with the brake lights if they are too close together. And the rear fog lamps are more penetrating (the fog lamps are the brightest of the various lights in the vehicle's configuration).

SoThe main reason for installing only one rear fog light is to distinguish between rear fog lights and brake lights

In addition, in our country, the rear fog lights of vehicles are generally on the left (not on the right or in the middle). This is due to the fact that the main driver's seat of the car in China is on the left, and the rear fog lights are set on the left, which can allow the driver to intuitively see the position of the vehicle, which is convenient for the next step of judgment and operation.

Hello, this one is different according to the model, some cars are two and some cars have only one.

Theoretically, there is only one car, so why is there only one?

In fact, the reason for this is very simple, you can think about what the role of the rear tail lights is, the rear tail lights are mainly foggy days, or need to be turned on when on the highway, the purpose is to take a car driver behind to see.

In the case of poor line of sight of the driver behind, in order to ensure safety, the distance from the front car is determined according to the position of the rear fog lights of the front car.

The position of the rear anti-fog lamp is generally installed in the left rear of the car, which is to allow the driver behind to see, and the light on the right rear side of the car, the driver behind is inconvenient to observe.

Therefore, there is generally no need to press the rear right, and one less installation is also a way to save costs.

The reason there is only one rear fog light is to distinguish the rear fog light from the brake light, so as not to be confused with the brake light. Introduction to Fog Lights: Cars are exposed to harsh climatic conditions such as fog, snow, and heavy rain. Fog lamp principle: The filament of the light source is designed on the focal point of the parabola of the mirror.

The rear light is in the car's **, of course, it is used one.

The front two fog lights are to look at the left and right corners in front of the car when moving forward to enhance the line of sight, and the rear fog lights are to remind the rear car to keep the driving distance

What did you do when you inspected the car? I found out about this when I inspected the car, and it was useless to say anything, and I had to install one after the high and low after-sales.

There is only one reason for the rear fog lights of a car: the main reason is to distinguish the rear fog lights from the brake lights. According to EU ECE R38 legislation:

If two rear fog lights are installed at the rear of the car, they must be at least 10 cm away from the brake lights. Because the rear fog lights are the same as the width indicator lights and brake lights, and the rear fog lights and brake lights are too close to each other, which is easy to be confused with the brake lights, and the rear fog lights are more penetrating.

There is only one reason for the summary of rear fog lights:

1. According to the EU ECE R38 regulation, most EU countries allow: one or two rear fog lights. If only one rear fog lamp is configured, its position can be in a

The body is positive**, or bIf two are configured on the same side as the driver, they must be symmetrical;

2. However, because the two rear fog lights are indeed easy to be confused with the brake lights, it is stipulated in ECE R48 that if two rear fog lights are configured, the position of the rear fog lights must be more than 10cm away from the brake lights.

3.The brightness of the rear fog lamp is specified in EEC 77 538: within the viewing angle range of 10 degrees on the horizontal axis and 5 degrees on the vertical axis, the illumination shall not be less than 150cd, but shall not be greater than the lampshade area of the rear fog lamp of 300cd, shall not be greater than 140 square centimeters, the color must be red, and the color temperature shall not exceed the 2854K of the CIE standard.

4. ECER 38 also stipulates that the rear fog lamp can only be turned on when one of the front fog lights, far lights or near lights is lit, and the rear fog lamps must be turned off manually without turning off the front fog lights.

5. The dashboard in the car indicates that the rear fog lights are lit relative to the signal, and the Biyan banquet must be (yellow). Only vehicles before January 1981 can use green.

6. Rear fog lamps were first used in Europe in the 1950s, and were introduced into the United States after the late 1980s (until the early 1990s).

7. Regulations of the United States and the European Union: at least one reversing lamp (so there is no need to install two).

Because the rear fog lights are the same as the rear width indicator and brake lights, but the rear fog lights are more penetrating, that is, more dazzling. Therefore, in order to clearly distinguish the rear fog lights from being mistaken for brake lights by the rear car, the design idea of "only one" was adopted, and a single rear fog light was located on the side of the driver's seat. But there are also many cars where the reversing lights are two symmetrical white lights, and only one fog lamp is empty on the other side.

Since drivers drive a lot, their sensitivity to lights is greatly reduced, leading to a gradual paralysis reaction. If there are two rear fog lights, it won't have much of a cue effect. If it lights up at the same time, they will feel normal and ignore it.

As a result, one rear fog lamp grabs the driver's attention more than two.

Moreover, since most domestic vehicles drive on the left, only a few drivers of Hong Kong and Macau cars drive on the right. And all of our countries are right-hand driven, the rear fog lights are on the left side, and the driver's position is the same, you can see the position of the vehicle more intuitively, and quickly make the next move.

Therefore, there is only one rear fog lamp of the car, which is based on science, not a "simple match" of automobile manufacturers.

Nowadays, cars are appearing more and more frequently in people's lives, and people are more and more aware of cars, but the more familiar they are, the more problems we encounter. For example, why do so many cars only have one reversing light?

For this phenomenon, in life, some netizens and friends will have the idea of pretending to be another one. If they go further, if they sell this problem to 4S stores, it is estimated that they are also stupid.

The function of this reversing light should be clear to everyone. Its most important function is that when reversing at night, the rear of the car is not visible, and can be used to illuminate the line of sight. But why do some cars only have one?

In fact, this matter has a lot to do with national regulations.

According to the relevant national regulations, as for the reversing lights, if the length of the vehicle is less than 6 meters, a Wuqin section must be installed, which is mandatory, and another sail can be installed as an option. Therefore, many car companies have installed one and reduced the other for the sake of cost. Similar regulations, there are fog lights.

Generally speaking, according to the national mandatory regulations, if only one is installed, it must be on the left side.

Of course, this reversing light is still good for the driver, which can attract the driver's attention and make the driver pay more attention.

Another reason is that the meaning of the reversing lights is not so much about lighting, but more about warning pedestrians and vehicles behind the vehicle. Remind the vehicle to reverse. It's driving, which means you're reversing. Attention everyone. And for such a role, one is enough.

Generally speaking, car companies do this for cost savings as well as for practicality.
