The following are the performances of different color temperatures: light color temperature, light efficiency of 3000K yellow light, strong penetration of 4200K, xenon lamp with light of 5000K in the original car, the highest color temperature of 6500K K in Europe, and fluorescent lamp with blue color of 7000-8000K in sunlight, slightly blue, with poor penetration. To sum up, many friends think that the higher the color temperature, the better. The color temperature of almost all xenon lamps in the original factory is only 4000k, because the higher the color temperature, the bluer the color, but the penetration is poor, especially in rainy and foggy days. This is easy to understand, just as few street lamps are blue. Moreover, the color temperature has nothing to do with brightness, and brightness is only related to lumen value. That kind of 8000K, even 10000K, blue is terrible, and it can only fool those car owners who don't understand cars and only pursue dazzle. Then the second question is coming. What kind of color temperature can ensure bright and dazzling and strong penetration? The answer is: different color temperatures show different penetrating power in different environments. Although there is no conclusion so far, it is not difficult to distinguish from the actual situation: for example, under good lighting conditions, the sensitivity of eyes to light with a wavelength of 550nm (yellow light) is 20 times that of red light or blue light. However, under dark lighting conditions, the situation is just the opposite. Expert recommendation: The color temperature around 6000K is just the whitest temperature that starts to turn slightly blue, which is easy for human eyes to accept, not easy to fatigue, and the safety is improved, while halogen lamps are poor. Experts believe that 6000k HID is the most suitable, because it is closest to the sun and most comfortable. Its light is super white and slightly blue. Some drivers may ask that the xenon lamp on BMW Benz looks blue, and sometimes it even turns purple. Even the color temperature of 6000k can't produce such a color. Answering you with the reply of my rider upstairs is actually because of the camera. It turns out that the beautiful blue and purple of xenon lamps are all modified by high-quality lenses, not high color temperature. Through high-quality lenses, penetration can be enhanced and good dazzling effect can be maintained. X key signal lights are used for different lights, including turn signal lights (double flashing) and brake lights. Proper use of traffic lights is very important for safe driving. Let's talk about the turn signal first. This light is turned on when the vehicle turns, and flashes intermittently to remind the surrounding vehicles and pedestrians. The turn-on time of the turn signal should be controlled well, and it should be turned on when it is about 0/00 meters away from the turning intersection/kloc-. If you drive too early, you will have the illusion of "forgetting to turn off the turn signal" for the following car. If you drive too late, the cars and pedestrians behind you will be caught off guard and often make mistakes in your busy work. Let's talk about the brake lights. This light is very bright, which is used to inform the rear car that the front car should slow down or stop. If this lamp is not used properly, it will easily lead to a rear-end collision. In addition, drivers should be reminded to pay attention to the replacement of brake light bulbs: domestic taillights are generally "dual-purpose", and there are two filaments in the bulb, the weaker one is the small light and the stronger one is the brake light. Some manufacturers design it as a high-low pin type, which is very convenient to use. Be careful not to connect it backwards when replacing it. Nocturnal width indicator light, commonly known as "small light". This lamp is used to show the width and length of the car body at night. When carrying out routine maintenance, the driver should always check. Some drivers think that the small lights don't work and they don't pay enough attention to them, which is very wrong. Fog lights can help drivers improve their visibility when driving in foggy days, and can ensure that oncoming cars can be found in time, so as to take measures to meet them safely. Therefore, drivers must turn on fog lights when driving in foggy days, and can't use small lights instead. Night lighting, commonly known as "headlights". Headlights are the "heart" of all headlights. Use headlights reasonably, change them into low beam when overtaking, and change them into high beam in time after overtaking, so as to broaden the horizons and make up for the unclear vision caused by overtaking. When overtaking at the intersection, you should change the warning of the far and near lights.
