[Car owners’ home car knowledge]We have introduced to you some of the most popular headlight modifications at present. From the perspective of night driving safety, more and more car owners have entered the field of modification. Modification of xenon headlights has long been commonplace. As for the modification of lenses, many netizens have expressed great interest. Today we will talk about the modification of headlight lenses.

The benefits of installing lenses are very obvious, especially for some original halogen lamp models without lenses. After the modification of xenon headlights, due to the change in the position and shape of the bulb, the original lamp bowl can no longer effectively focus the xenon bulb. The light pattern is scattered, which not only makes the driver unable to see the road. It will also dazzle other people on the road, which is useless! Using optical principles, the lens can illuminate the light on the road at the most reasonable angle to solve the above problems, which is the biggest advantage of the lens. Usually, the lens can be divided into two categories according to the tangent line of the light: European standard light type and American standard light type.

Usually, the lens can be divided into two categories according to the tangent line of the light: European standard light type and American standard light type.



☆ Distinguish by light type:

The so-called European standard light type has large up and down radiance, and there will be more dark areas on the left. This is mainly to avoid dazzling each other when meeting cars. However, for SUV models with taller bodies, because the lamp position is higher, in order not to affect others, the illumination angle must be lower (than that of a car). (adjust more angles below), which will make the dark area on the far left (left-hand drive vehicle) more obvious. The American standard light type adopts a design with almost equal heights on the left and right, and the illumination angle is wider. It has obvious advantages in suburbs or some places with poor road lighting conditions.


There is also a type called mixed standard light pattern, which compromises the characteristics of European standard and American standard light patterns. It can better take care of the field of vision of oncoming vehicles without causing too many dark areas on the left side.
☆Bifocal lens and single vision lens:
The bifocal lens actually only uses one bulb, but it can switch between high and low beams through the light shield inside the lens! When the light shield is closed, it is low beam, and when the light shield is open, it is high beam. The light bulb inside the lens does not move. The installation of a bifocal lens means that a xenon bulb plays two roles: high beam and low beam. The simple identification method is to see if the lens has a dimming solenoid valve. If it has a solenoid valve, it is dual light, otherwise it is single light.



☆ Common imported lenses:
The most common Hella brand is made in Germany, and the so-called domestic products are all fakes. Hella, Koito and other lenses require holes in the original lampshade before they can be installed (unless it can be directly installed on the corresponding car model), and there are almost no new products. Most of the ones purchased in China are dismantled car parts. Therefore, when buying lenses of this brand, in addition to carefully observing whether the lens is intact, it is equally important to find a responsible store. In terms of price, since they are dismantled car parts, they usually cost more than a thousand yuan (the chaotic market also leads to large price differences). However, if there are sellers selling big-name lenses like Koito and Hella for two to three hundred yuan, or even claiming to be brand new, then don’t think it must be a fake. As for domestic brand lenses like Haidi, although the optical performance is somewhat inferior to that of big brands like Hella and Koito, there are fewer fakes.

In addition, there is currently a more popular modification method in China, which is to directly replace the produced headlight assembly. Compared with a series of processes that test the skills of technicians such as cutting the lamp bowl and installing the lens to modify the lens, directly replacing the assembly with the lens and angel eye/devil eye seems to be safer, but in fact, the headlight assemblies currently sold on the market (mostly with lower prices) Many of them (mainly for high-end models) are made by unknown small workshops. The quality of the lenses, the workmanship of the lamp bowls and the materials used for the lampshades are uneven. The durability is even more worrying, because the heat emitted by the headlights is much greater than that of the taillights, and the heat resistance of the lampshades and bowls is required to be higher. For car owners who want to improve the convenience of driving at night, modifying the headlights should be a priority.

☆ Common faults of modified lenses: fogging and water intrusion in car headlights
With the popularity of modified car lights, a problem that has attracted much attention has been increasingly mentioned by car enthusiasts, that is, headlights fogging up and water entering. Fogging inside the lampshade is mostly caused by large temperature differences, and is most likely to occur in winter and rainy seasons. In this case, you don't have to worry too much. After the car lights are turned on for a period of time, the mist will be discharged out of the lights through the vent pipe along with the hot air. This will basically not damage the headlights and electrical circuits.
Water intrusion into the headlight means that water accumulates in the headlight, and large water droplets adhere to the inner wall of the lampshade, which cannot dissipate on their own in a short period of time. This situation is a headlight sealing problem and is abnormal. Many cases of water entering the headlights are caused by workmanship problems when modifying the headlight lenses, and some irresponsible store owners will use various excuses to shirk responsibility. For example, due to the low heat of xenon headlights, the lens absorbs a certain amount of heat, causing water vapor to evaporate slowly, etc.

In order to prevent fogging and water intrusion as much as possible, it is obviously necessary for us, as car owners, to choose a good store that is responsible and has a good reputation. At present, modified headlights are very popular in China. Many cities have active local car clubs and other non-governmental organizations. Before modifying headlights, it is best to find more car owners who have experience in modifying headlights to learn from them, or to find an experienced modification shop through a specialized modified car light website for installation. To make a digression, the products currently sold in the domestic modification market and even the auto parts market can be said to be mixed, and it is very common to pass them off as good, especially for modified headlights, a relatively popular modification and upgrade project. Do not spend blindly. Before modification, you must weigh the pros and cons, and protect your rights and interests as much as possible.
☆Personalized headlight modification:
In addition to improving the performance of the car's lighting system, most modifiers also have their own personalized needs. Many people will replace appearance kits, change colors, etc. for their models. However, these modifications are difficult to see in the dark, so some people will think of making personalized modifications to the lighting so that people can see the special features of the vehicle in the dark.



In addition to the angel eye and devil eye modifications that have become more popular in recent years, LED decorative lights have also become popular. LED lights have the characteristics of large amount of light, low power consumption, durability, etc., and most importantly, they are small in size, allowing great freedom in installation and display. Models such as Audi and Lexus use LED technology as the main light source of lighting (it is still a new technology and has not been popularized yet), and many models use LED to make daytime running lights, which not only improves the safety of the vehicle but is also very beautiful. There are many options for the installation position of LED lighting to create different effects, which provides a lot of freedom for car owners who like to modify the appearance. For example, it can be installed on the front bumper or fog lamp as a daytime running light, or it can be installed on the bottom or top of the headlight to create an "eyeliner" decorative effect, and the styles are very diverse.
