There are many kinds of lights on the car body, and daytime driving lights are often overlooked by drivers because of their use characteristics. Even the old drivers who have been driving for many years may not be able to use the daytime running lights correctly. What is the use of daytime driving lights? When should I use it? Let Xiao Bian explain it to you.

What is the use of daytime driving lights?

Today's daytime driving lights have a wide variety of styles, making them more and more cool, and even some owners have to change the daytime driving lights in order to make the lights more cool. However, you should not think that the daytime driving lights are just decorations. It plays a very important role in driving safety.

Daytime Running Light, or DRL for short, is the name of the daytime running light. First of all, its role is not to illuminate, but to make the front and the opposite vehicle notice the location of the vehicle you are driving. This is its most fundamental. Design original intention.

Second, when do you use daytime driving lights?

Daytime driving lights, as the name implies, are used during daytime driving. Some people may ask, is it still so bright during the day? Xiao Bian explained to you. As we all know, the air is not pure and transparent. There will be many things that will affect the line of sight. The earthworms, dust particles, and moisture will all float in the air, affecting our observation of distant objects. At the same distance, the luminous object is more conspicuous than the non-luminescent one.

Sometimes, from the driver's point of view, visibility and light are good, you can see, but other vehicles may not be able to see you at this time, for example: If you drive in the evening, Shunguang Driving, fiery sunset behind you, the front of the situation are very clear, but the front of the car to see your car may be very vague, because his rearview mirror can only see the sunset, and your car It is "backlit" in the rearview mirror of the front vehicle, and if you can't see clearly where you are on the opposite vehicle, the risk factor is even greater.

In another case, when the vehicle passes under the overpass in the city, the light under the bridge is much darker than the outside, so vehicles without light are very vague under the bridge and are not easy to see, even if there is automatic The lamp's model also has a short-term hysteresis before it enters the bridge. The headlights will light up. If you enter the bridge and enter the line, it is possible to ignore the rear of the car without any light.

Beijing, which is often covered with haze in recent years, needs a daytime running light. When the haze is severe, the effect of switching on or off is not the same even when the distance is 200 meters. Far!

Daytime running lights during the day, one can improve the visibility of vehicles in the sports, help drivers to take timely measures to meet the situation; the second is conducive to the concentration of drivers, especially the driver of fatigue driving. It is understood that turning on daytime driving lights while driving can reduce vehicle accidents by 12.4%, while reducing the chance of 26.4% accident deaths.

Third, how to use daytime driving lights?

Unlike other car lights, the daytime running lights do not switch (except for the daytime driving lights modified later) and cannot be turned on or off at will. It usually starts automatically with the start of the engine and turns off automatically when the driver turns on the conventional light.

Fourth, note: at night only driving lights in the day is not desirable!

Xiao Bian recently observed a segment of it. Some drivers only drive a daytime driving light when driving at night. This is totally wrong!

Daytime driving lights are mostly LED light sources, reflected by the reflectors to the front, so the light is not directed to the road, in the evening to see the daytime driving lights shot out of the light is scattered, although from the outside Very bright, even dazzling, but from the perspective of the inside of the car is not better than no lights, the front is still dark, and the seemingly dazzling daytime driving lights are not open to the people in the car. Like a lamp. The difference between the two is more clear when you turn on the low beam. Therefore, it must be remembered that the daytime driving lights are just a reminder, and you can never use it as a lighting tool! Always use dipped headlights in dark places and at night (daytime driving lights turn off or dim when the width or dipped headlights are turned on.)

From a different point of view, in the poor lighting conditions in the evening, the daytime driving lights will be more dazzling, and will seriously affect the sight of the opposite vehicle and the front of the car.

Therefore, Xiao Bian reminds you that if you only turn on daylight in dark conditions, you will not be able to obtain good lighting effects for the driver, but it will also affect the sight of the opposing vehicle and the vehicle ahead, which will easily lead to traffic accidents. This is not responsible for yourself and others.
