Car headlights take a long time and need to be replaced. At this time, it is necessary to modify the headlights. Today, Xiaobian will introduce various car headlights and discuss how to choose car headlights to be the most practical. The headlights on the market include halogen headlights, xenon headlights, LED headlights and laser headlights.
Halogen headlight
Halogen lamps are generally divided into: iodine tungsten lamps and bromine tungsten lamps, which are actually a special type of incandescent lamps.
Low cost and fast start-up speed. Many entry and low-end models will choose halogen lamps, which has the highest penetration rate in the market.
Rain and snow have strong penetrating power and are more penetrating than xenon lamps. Some off-road vehicles also choose to install halogen lamps.
Insufficient brightness is the biggest drawback of halogen lamps. The road lighting effect is not as good as that of xenon lamps and LED lamps. It has better lighting effect when used with reflectors. The service life is short, about three years.
Xenon headlights
Xenon lamp, the full name is HID (High Intensity Discharge Lamp) gas discharge lamp.
Xenon lamps are three times more powerful than halogen lamps, greatly improving driver safety and comfort, and consume only two-thirds of the cost of halogen lamps. However, the startup speed is slow. After the headlights are turned on, it takes three to four seconds to achieve the best brightness. At present, it accounts for a large part of the market share of headlights, such as some medium and high-class models.
