How to correctly choose safe and effective headlights

The importance of car headlights for driving safety is naturally self-evident, especially at night, we need car headlights to illuminate the driving vision, and at the same time warn and remind other vehicles or pedestrians.

Therefore, the correct selection of safe and effective car headlights is very important.

At present, the mainstream car headlights mainly include LED headlights, xenon headlights or halogen headlights. The author will introduce the characteristics of these three headlights respectively, and give you a reference for choosing car headlights.

The brightness of halogen headlights is much inferior to other headlights, and the light source is mostly yellow.

Most of the early halogen lamps were used in conjunction with bowl-shaped lampshades. Nowadays, halogen headlights are also equipped with lenses. The life of halogen headlights is relatively short, and after a long period of use, there will be blackening. However, the penetration ability of halogen headlights in rainy and foggy days is still very good. For example, our fog lights use halogen headlights.

The cost of halogen headlights is very low, and the price is cheaper than the other two headlights.

Then came the xenon headlights. The brightness of xenon headlights is much better than halogen headlights.

The xenon lamp is a heavy metal lamp, which is filled with a variety of chemical gases, such as xenon and other inert gases, in a UV-resistant crystal quartz glass tube. Then through the supercharger, the on-board 12-volt power supply is instantly increased to 23,000 volts. Under high voltage, the xenon gas will be ionized and generate a light source between the two poles of the power supply.

Xenon headlights are much more complicated than halogen headlights. Therefore, replacing xenon headlights is not only as simple as replacing the bulbs (xenon headlights include bulbs, ballasts and supporting wire sets).

Behind is the LED headlights. The brightness of the LED headlight group is very good, and the penetrating ability is also very good, and the LED headlight group has low energy consumption and long life, which is the overall performance of the three headlight groups. Therefore, more and more vehicles are now using LED headlights. However, the cost of LED headlights is higher.

In summary, I suggest that you choose LED headlights, followed by xenon headlights, followed by halogen headlights.
