How much does it cost to replace a car headlight? Friends who have never replaced them may not realize how expensive car headlights are. Brother Agui will give you a reference price here. The earliest halogen headlights only cost tens to 300 yuan to replace. As xenon lamps are more powerful than halogen headlights, they cost between 300 and 3,000 yuan. The latest LED headlights, the replacement price depends on the price of the car, ranging from 1,500 yuan to 30,000 yuan, and the headlights of some luxury cars can even cost hundreds of thousands.
Are car lights different from street lights? Why is it sold so expensive? Could it be that he is robbing customers?
In fact, this is not the case. The seemingly "simple" car headlights are really expensive for a reason.
First of all, how many types of light modules are integrated into a car light?
Take the latest LED headlights as an example, which include four types: daytime running lights, turn lights, dipped beams, and high beams, plus the overall LED lighting control unit and adjustment structure. If these modules alone are combined The total cost of materials may not be too high. You can buy finished modules on a certain website for only three to four hundred yuan. Some friends who are good at DIY have even made some similar ornaments for fun.
But it is a pity that these modules need to be applied in cars, so various designs need to be added to ensure that the car lights have strong stability. This also results in that in addition to material costs, the research and development costs of car lights have also become very high.
First of all, from the overall structure, due to the characteristics of LED headlights, they need ventilation to dissipate heat. Therefore, where the breathable structure is left can it effectively dissipate heat, but it cannot cause fog inside the headlights to affect the lighting conditions when there is sufficient water vapor. That's a problem.
In addition, how to arrange the positions of different lighting modules in a limited space without affecting each other is also a problem. After all, LED lights are really hot. After solving these, you have to start to consider the shape and material of the plastic shell in front. After all, as the shell of the headlight, it cannot get hot or yellow, how to place the internal ribs that affect the shape of the light, etc. .

After solving the problems of material and structure, this lamp can only be said to be usable. As an important part of a car's appearance, headlights must be designed to be aesthetically pleasing, such as where to add chrome plating, where to fit the design language of the entire vehicle, etc. After this plan is basically completed, it needs to be sent for stability testing to ensure that the car lights can operate normally in all kinds of harsh environments that you can't even think of. For example, you may have never thought about driving in the desert for ten consecutive hours without turning off the high beam, and whether the car lights will melt or have other problems if they are exposed to the double irradiation of the sun and the internal LED lights. . But designers must think of this problem and verify it. After testing dozens or even hundreds of versions of car lighting solutions, the finalized lights will be used on cars as original lights.
It is precisely because of the need to amortize these costs that the price of car lights can sometimes be completely unexpected (of course there are also brand premiums for some luxury brands). Okay, that’s the end of this issue. I wonder what is the most expensive car light you have ever replaced? Can you quote a price in the comment area?
