Generally speaking, it is composed of all other luminous lamps and electronic circuits except signal lamps. Headlights usually refer to lighting bulbs, and the assembly connects wires, circuits, lighting controllers and so on.
The headlight assembly also includes a width indicator for night driving. Tell other drivers where they are. It plays a safe role in driving at night. The headlamp is installed in the middle of the headlamp assembly. Generally speaking, the headlight of a car is a light bulb with low beam and high beam lines. Just control the light to switch the distance of the beam.
There are two forms: a two-lamp system with one side high beam and low beam (double headlights), and a four-lamp system with one side high beam and low beam separated (four lamps).
At present, many car headlights are equipped with automatic lighting controllers. The light beam can be automatically adjusted when passing. Do not interfere with each other. And the driving safety is improved.
Under what circumstances should the headlight assembly be replaced?
It is reasonable to say that the headlight assembly is original, but it is often turned on and off, which often leads to problems. When the headlight assembly cannot be restored to the safe driving demand through maintenance, it will be replaced, mainly because it does not meet the requirements and may not pass the annual inspection. The law stipulates the power and brightness of high beam. The high beam can't be changed randomly, it will be checked by the traffic police, and it will not pass the annual inspection. This is the result that many car owners often get feedback.
Headlight assembly basically does not need to be replaced, unless you want to be cool, or the original headlight assembly can no longer be used. Generally speaking, except the light source, the assembly can only be replaced after other parts are broken.
Modification of halogen lamp into xenon headlamp assembly
If your headlight assembly has no lens, it is best not to add xenon lamp directly, because the lampshade of traditional halogen lamp can't concentrate light at all, and the light will definitely diverge.
Although some cars are also equipped with halogen lamps, the modification effect is relatively good because of the lens in the assembly. Of course, it still needs technicians to adjust, and the focal length is very complicated, because the length of xenon lamp tube is different from that of halogen lamp.
The lens of xenon lamp assembly is still different from that of halogen lamp. A truly well-made xenon lamp lens should not only have good condensing performance, but also have beautiful color transformation. With the ups and downs of the road surface, the color will flash purple and blue from a distance, and it will be pure white light with the same color temperature as sunlight from a close distance.
Special attention: Some cars can never directly replace xenon lamps, that is, those cars that use the H4 lighting assembly with integrated far and near light. The lights of this car are so scattered that the driver opposite you thinks you are driving a low beam.
Which brand of headlight assembly is good?
With the popularity of automobiles, there are more and more manufacturers and brands in car headlights. At present, there are many headlight assembly brands in the market, such as Foshan Lighting Brand, Philips/Philips Lights, Bosch Lights Brand, Caster Lights Brand, Osram Lights Brand, Shanghai Xiaonan Lights Co., Ltd., Changzhou Chineydy Lights Co., Ltd., etc. As for which brand is better, it has something to do with the matching degree of the car, depending on which brand is used by the original factory.
Of course, some car manufacturers will not use the best brand headlight assembly because of the cost problem. You can choose a car that suits you.
Headlamp assembly price? How much does it cost to change a headlight assembly?
This question is a bit too big to answer directly. The difference between halogen lamp and xenon lamp will affect the price of headlight assembly for cars with different price points. At present, in addition to the problem that the original components can't be used and need to be replaced, more demand is that halogen lamps need to be replaced when they are converted into xenon lamps. Conventional family cars can generally be replaced around 1000. Due to the relatively low technical standards for access, the price range is quite large.
