The service life of halogen lamp in automobile is based on the fact that the bulb is damaged or not on. No matter what the reason is, not on proves that the life of the bulb has reached the limit and cannot be used. Halogen bulb is the most common type of automobile. The life of halogen bulb in automobile is four times longer than that of ordinary incandescent bulb. Theoretically, the cumulative use time can reach about 300 hours. If you drive three nights a week, the halogen bulb can be used for three to five years. During this period, the brightness of bulb will gradually decline. The bulb is filled with two gases, i.e. iodine and bromine, as well as a tungsten wire. After electric heating, the tungsten wire is heated and glows. When the tungsten wire is heated, it will sublimate tungsten. After the chemical reaction between tungsten and iodine bromine gas cools, it will re solidify on the tungsten wire, avoiding the problem of premature fracture of tungsten wire. Its biggest advantage is low price and good penetration.
