【Owner's home car knowledge】Car lights, as an important part of car functions and the finishing touch of car body appearance, its most basic function-safety, is often ignored by some car owners. Sweden and Canada stipulate that driving lights must be turned on during the day. According to statistics, 60% of car accidents are caused by unclear vision. Therefore, many high-end luxury cars and European cars regard automatic headlights as an important and basic active safety configuration. Now in China, we can often see that some cars have daylight lights that are always on in some high-end cars in China. This is an automatic setting when the vehicle leaves the factory. For safety reasons, it is not because the lights are broken or the owner's own behavior.
In Sweden and Canada, because the weather is dark and often snows, it is stipulated that the headlights must be turned on during the day. This kind of regulation has begun to prevail in the European continent, and it has also begun to be tried in some parts of Zhejiang Province in my country. In order to prevent the occurrence of traffic accidents, the Jinhua City Traffic Patrol Detachment issued the regulation of "turning on the headlights when driving on the Hangzhou-Jinhua Line during the day".

In order to prevent the occurrence of traffic accidents, the Jinhua City Traffic Patrol Detachment issued the regulation of "turning on the headlights when driving on the Hangzhou-Jinhua Line during the day". According to statistics, during the pilot period of more than four months, the four indexes of traffic accidents have all declined, and the number of traffic accidents to the police has decreased by 13.6% year-on-year. Turning on the headlights when driving during the day is not for the needs of lighting, but for other pedestrians and motor vehicles to see their own cars as soon as possible, so that the other party can prepare as soon as possible to ensure safety.
Therefore, for the sake of safety, many high-end cars have the function of automatically turning on the headlights, especially in European cars.
Why is it safe to turn on the headlights under gray light? First, let's analyze the human eyes. At dawn and dusk, the human eye's ability to recognize colors and shapes is the weakest, and the pupils are in an alternate working state of day and night. At this moment, the light is insufficient, that is, the feeling of grayness (and the pollution of the city has deepened this situation), the target that can be clearly judged at a distance of 300 meters, generally has to be zoomed in to 50 meters at this time.
Now look at the color of the car. According to statistics, almost 1/3 of consumers choose silver-gray cars. And silver-gray is a good camouflage color, it is easy to blend into the gray background, it is not easy to distinguish the shape, it is usually used in fighter jets, so the role of automatic headlights is revealed at this time. Because turning on the headlights is not only to let yourself see the road situation clearly, but also has an important role in letting others see your car.
Another situation is to enter an underground garage or tunnel. Because the light changes from bright to dark, human eyes have an adaptation process, so the sensitive automatic headlights will give the driver additional light compensation at this time. In most rainy and snowy weather, the vision is not good, and the background will appear gray. At this time, turning on the lights can improve the attention of yourself and other vehicles.
Vehicle lights are not bright enough can be improved through some simple methods
The lighting of the vehicle is designed by the car OEM. But if you feel that it is not bright enough, there are some simple ways to improve it.
There was a problem with the lamp itself. For example, the inside of the lampshade is too dirty; the use of fake and inferior lampshades, and the external grinding and fading will affect the light emission. The lampshade can be removed for cleaning, or simply replaced;
Impossible to boost power
The easiest way to increase light is naturally to increase the power of the headlights. Although this method is relatively low in cost and simple in construction, the effect is limited and there are certain hidden dangers. Replacing a 50W headlight with 100W will not simply double the brightness. On the contrary, due to the increase of power, the damage of the line will increase accordingly, causing the line to heat up, accelerating the aging of the wire, and the voltage at both ends of the headlight will drop. Most of the results like this are: the brightness only increases a little, but it will cause the line load to increase, bury the hidden danger of accidents, and the lampshade and the lamp bowl all have the danger of deformation and discoloration due to excessive temperature.
HID rainy season effect is poor
HID gas discharge lamps are often called xenon lamps. The advantages are high brightness, high color temperature, long life, and low energy consumption; the disadvantages are high price and difficult installation. Forcibly modified xenon lamps will cause the light distribution of the original car to fail to meet national standards, while the price of lamps that can meet the original lighting standards is low. Surprisingly high. The main problem is that the color temperature of HID lamps is too high, so the penetrability of the lights in rainy and foggy weather is not even as good as that of ordinary car lights, so it is not recommended.
