The smog has become more and more serious recently, and buses in Chengdu are free to ride. Driving in this kind of weather is more terrifying than foggy days, but you can always see various cars on the road confidently driving forward with double flashes. , or silently turned on the headlights.
Do you really not know about fog lights?
Fog lights, as the name suggests, are lighting groups used in foggy days. The function of fog lights is to allow other vehicles to see the vehicle in foggy or rainy days when visibility is greatly affected by the weather. Therefore, the light source of the fog lights needs to have strong penetration. Generally, more penetrating halogen fog lamps are used.
But as mentioned at the beginning, many people now don’t even know what fog lights are. If they still turn on double flashers in heavy fog, you should at least turn on a width indicator light, right?
What do fog lights look like? When to use it?
As a fog lamp that is not commonly used, its appearance is inconspicuous. Most of the front fog lamps are equipped under the bumper, which makes it easier for the light to diffuse and illuminate the road ahead, while the rear fog lamps are mostly located at the innermost position of the rear headlights. , and in order to prevent the driver behind the car from thinking it is a brake light, many will only be equipped with a single-sided rear fog light.
Fog lights can only be installed below the bumper and where the car body is closest to the ground to ensure the function of the fog lights and ensure that the light penetrates rain and fog to illuminate the ground (fog is generally thinner below 1 meter).
The markings of fog lights in the car generally look like this:
Its switch button should look like this:
Need to say more about how to use it?
On foggy and rainy days, just turn it on. This can not only protect your own vision, but also provide other vehicles with their own vision, greatly avoiding traffic accidents.
Why do many high-end cars no longer have fog lights?
I believe this issue is also of concern to many people. Nowadays, many vehicles do not have fog lights as an option at all, not even as an option.
In the early years, halogen headlights were used for vehicle lighting, and fog lights were equipped underneath. Later, xenon headlights were used, but the penetrating power of xenon headlights is not as strong as halogen lights, so for safety reasons, many models are still equipped with halogen lights. source of fog lights.
But the problem is that many domestic driving schools purchase low-end cars. In order to save costs, they omit the option of fog lamps. Moreover, there is no mandatory requirement to equip fog lamps in national regulations, and the driving school examination does not test the use of fog lamps. Over time, the width indicator light became a common light in heavy rain and foggy days.
Subsequently, market competition intensified, joint venture brands increased, independent brands emerged, luxury brand prices dropped, and price wars continued. Fog lamps, a configuration considered dispensable, were naturally omitted, and there are many of them now. For entry-level joint venture sedans, the entry-level version almost does not have fog lights.
So here comes the last question, why are many high-end cars not equipped with fog lights?
In fact, it is equipped, but it is not released separately, but integrated into the headlight group. This not only adds more design space to the designer, but also saves the trouble of turning on the fog lights separately.
It should be reminded that although high-end models have integrated fog light functions, most ordinary family cars do not have this feature in their lighting groups, so you still need to pay attention to whether they have this configuration when buying a car.
Finally, on foggy and rainy days, do not turn on double flashers, but turn on wide lights or fog lights.
