The lifespan of automobile halogen headlights is about 4 to 6 years. In theory, the cumulative use time can reach about 300 hours. If you drive at night on three days a week, the service life is this time, but it depends on the night and before you drive. The use time of the lamp (day or night). The biggest disadvantage of halogen lamps is that the brightness is weak, which cannot satisfy car owners who have high requirements for lighting. Its biggest advantage is that it is cheap and has good penetrating power.

Types of lights

The halogen bulb is the most common type of car. It works the same as the incandescent bulbs used in the home. The bulb is filled with two gases, iodine and bromine, and a tungsten wire. After electric heating, the tungsten wire emits heat and emits light. When it heats up, it will sublime tungsten. After the chemical reaction between tungsten and iodine and bromine gas is cooled, it will re-solidify on the tungsten wire, avoiding the problem of premature breakage of the tungsten wire.

The xenon bulb is a quartz tube injected with xenon gas. The xenon gas in the quartz tube is activated by high-voltage electric current to form an arc. Many car owners choose xenon lamps because they have higher brightness than halogen lamps. To be three times higher, the color temperature of xenon lamps is generally between 3500K and 8000K. The lower the color temperature, the more yellow the color, and the stronger the penetrating power in rain and fog. On the contrary, the higher the color temperature, the whiter the color, and the worse the penetrating power in rain and fog.

LED lights are also known as light-emitting diodes. LED lights are the most popular car headlights. The price is about 2 times higher than that of xenon lights. LED lights are generally rarely installed on low-end cars, and most of them are used in high-end cars and On top of luxury cars, there must be a reason why it is expensive. The LED lights have high brightness, low power consumption, and almost no burnout problems. The service life can reach 60,000 to 100,000 hours. According to the normal vehicle usage time, the LED lights will not be damaged when the car is driven to the scrap.
