Read the production date of the car headlight, you can check the seal on the headlight, the position of the seal is generally at the lower left or right corner of the headlight, the production date of the headlight can be seen directly from the seal, of course , Each manufacturer may have different opinions on the seal, please consult the headlight manufacturer for details.
And if the relevant seal is not found, you should consider whether the headlight is a counterfeit product.
Precautions for replacing headlights
1. When choosing new headlights, you should choose the appropriate bulb model according to your own car. At the same time, you should consider the annual audit and whether the dfsk battery can withstand issues. It is best to choose the original headlights.
2. When disassembling and assembling, avoid touching the glass shell of the bulb with your hands. When installing the bulb, do not directly touch the glass body with your fingers, because only a little bit of grease sticking to the glass body will shorten the service life of the bulb. , There is a danger of bursting after long-term use.
3. When replacing the bulb, compare the illuminance and adjust it in time.
Attachment: Method of identifying original headlights
For the original headlights, the quality of the headlights of the sub-factory is generally uneven. There are many next times in the corners, and the logos engraved on the headlights are also blurred.
In addition, the sub-factory's lamp manufacturing level is insufficient, and the tolerances are not well done, resulting in uneven gaps between the lamp and the body.
The lighting effect of the sub-factory lights is not good, the response time is poor, and the brightness of the left and right lights is not consistent.
Which one is better, halogen lamp, LED lamp, or xenon headlight?
When driving at night, you will find that the headlights of many cars are very bright. If the opposite direction is shooting high beams, you can hardly open your eyes in the car.
At this time, there will be an idea in your heart that you want to modify the headlights of your car. So which is better for so many types of car headlights today? Many people may not be very clear. Today I will talk about some issues about car headlights.
halogen lamp
Let’s talk about halogen lamps. The earliest headlights on automobiles were these halogen headlights. For now, despite so many years of development, many low-profile models are still equipped with halogen headlights when they leave the factory.
Halogen headlights have the characteristics of simple structure, easy replacement, strong light penetration, etc. The most important thing is that they are relatively cheap. So many models are still equipped with halogen headlights.
LED headlights
LED headlights have appeared in recent years, and their principle is mainly to emit light through light-emitting diodes. LED headlights are characterized by low power and high brightness, so many high-end models now use LED headlights.
But there is a shortcoming before LED headlights, that is, the color temperature is usually higher, which makes the penetrability of the car lights relatively poor in the case of rain and fog. This is also a situation where many people do not recommend modifying LED lights.
But nowadays, LED car lights also have a certain development, and there are many LED car lights with variable color temperature, which also makes up for the shortcomings of dongfeng t5 LED car light color temperature.
Xenon headlights
Let’s talk about xenon headlights. Xenon headlights appeared earlier than LED car lights. Because of its high brightness, it has been modified by many riders.
However, due to the spontaneous combustion of xenon headlights after refitting in recent years, they have not been favored by everyone in recent years.
Which headlight is better?
In fact, to modify the headlights, for these riders, they are dissatisfied with their original lights and want to modify them into brighter lights.
Then LED or xenon headlights are a better choice. However, it is not only necessary to replace the headlights when refitting. The headlight lens needs to be refitted at the same time as the lights are changed.
Because the luminous points of halogen lamps, LED lamps, and xenon lamps are different, their lenses are not universal. When changing the lamp, if you just replace the bulb, not only will it not be too bright, but it will also affect the annual inspection.
