For now, there are still some cars, in the entry-level version, equipped with substandard halogen lamps. Due to the extremely poor lighting effect at night, they have been criticized by many experienced drivers. However, knowledgeable experienced drivers basically know that if they want to To solve this problem, you can do it perfectly for only two to three hundred dollars, and you don't even need labor costs, because you can solve it yourself.
Using the all-powerful treasure, you can also replace the headlights yourself
As far as the structure of car headlights is concerned, most cars are relatively simple. Just remove the original halogen headlights and insert the newly purchased LED lights. An omnipotent store even teaches you the three steps of installation and removal for free. Follow the "strategy" and then look at the price. There are dozens, more than a hundred, and more than three hundred, so you have to pay attention to how to choose at this time.
Be sure of the brand and be optimistic about the parameters
General brand-name products are relatively cheap, but relatively speaking, they are not as reliable as branded ones. Therefore, in this regard, Chelulu recommends that if you replace the headlights by yourself, you should buy branded ones, such as Philips and Osram, which are slightly more expensive. It only costs more than 300, but the quality is definitely more reliable than the brand-name products, and generally the parameters of such brand stores will not be fake.
It won’t be like some motley crew, whose parameters are boasted to the sky, but will be found to be fake upon inspection.
For example, the manufacturer claims that the brightness of an 80-100W LED headlight can reach 32800lm-35000lm. This data is very impressive, right? But as everyone knows, this parameter is simply wrong. Che Zhulu once found a formula for calculating the luminous efficiency of LED lights in a master's thesis. Generally, the brightness of 1W is around 80-150lm. To convert, even if it is 100W, we use 150lm. Calculated, it is only 15,000lm. If the difference is so big, it can only be said that the manufacturer is cheating.
Furthermore, the control of color temperature
Remember! The higher the color temperature, the better. Many people have always believed that the higher the color temperature, the greater the brightness. In fact, the two are not necessarily related.
The higher the color temperature, the whiter the light will be. After reaching a certain level, the car's lights will turn blue or even purple. Although it looks brighter, in fact its penetrating power is getting weaker and weaker. In rainy and foggy weather, you will know what pain is.
Generally speaking, it is enough to choose a color temperature between 4300 and 5000K, because it not only ensures a certain visual effect, but also ensures the penetration of light in rainy and foggy days. Relatively speaking, it is safer. If you choose a lamp with a color temperature of about 6000K , although the color of the light is closer to natural light, the visual effect is not bad when the weather is good, but it is a bit annoying when it rains and foggy.
In addition, I would like to mention that the brightness and color temperature of the light are not actually higher, the better. Although you can see more clearly, it will be a nightmare for the oncoming car when you meet the car. If you don't switch to the nearer in time, Lights may cause traffic accidents.
To put it simply, it is feasible to spend about 300 yuan to buy an LED headlight on a certain website and replace it yourself, but it is best for everyone to remember the above precautions.
