Hello everyone, this is a column focusing on car repair and maintenance. There are car secrets you don’t know here, and it will teach you how to avoid big pits on the road to car maintenance. I believe that not only you, but also many people have a certain hazy feeling about the automotive aftermarket. Here will help you uncover the unknown stories of car repair and maintenance.
Fog lights are the most common configuration on cars. Recently, Xiaobian received many messages from netizens. Netizens responded that they found that every car has rear fog lights, but not all front fog lights.
This issue of Xiaobian will show you an explanation: Why does your car have rear fog lights but not front fog lights?
1 What are fog lights?
Fog lamps are special purpose vehicle lights that are usually turned on in conditions of low visibility. Because the visual effects in foggy days are very poor and fog lights have strong penetration, they are collectively referred to as fog lights.
Of course, it also needs to be turned on when it rains, not just in foggy days. Regarding the specific use of fog lights, Xiaobian has written in detail in previous articles, so I won’t go into details here.
Second, why must cars have rear fog lights?
Our country’s transportation laws stipulate that as long as a vehicle driving on the road, it must have rear fog lights!
There are isolation zones in the middle of domestic highways. When driving, there is almost no need to care about vehicles in the opposite lane coming this way. It will be more meaningful to remind vehicles behind, so rear fog lights have become a standard configuration.
3. Why do some cars have no front fog lights?
Judging from the above, fog lights can play a great role in extreme weather. After configuring front fog lights, cars should be safer. Why are some models not equipped with front fog lights?
1 Cost aspect
The main engine factory will spend more money on fog lights, control lines, and control switches to install a set of front fog lights, and the production of a car will increase significantly.
Although it is cheaper to get goods from the main engine factory, it is scary if the quantity is large.
For a best-selling model, it is normal to sell tens of thousands of units a month. If the cost of installing a set of fog lights is only ten yuan and the sales of hundreds of thousands of vehicles a year, it will be a huge sum. Car manufacturers are not philanthropists, and they also have to consider costs.
Although cost is considered, front fog lights can still be seen on some high-profile models. Of course, these models have one thing in common, that is, the price is expensive enough.
2 Daytime running lights
In recent years, many models have begun to use daytime running lights on a large scale. Lower costs and more energy-saving methods have enabled daytime running lights to quickly occupy the market. Daytime running lights do not need to occupy a separate switch. As long as the engine lights are started, they will turn on and can serve as a warning at all times.
The emergence of daytime running lights is not only to make the car’s functions complete and beautiful, but also a hidden function is that it is gradually replacing traditional front fog lights.
IV Summary
This era is a survival of the fittest. When new technologies emerge, the old cannot escape the fate of being replaced, and the front fog lamp is one of them. As this technological trend blows, more and more automotive functions and configurations will gradually disappear, and this is the result of technological progress.
