HID (High Intensity Discharge Lamp), is the latest xenon car headlamp. This xenon lighting is quite bright, and its color temperature is similar to sunlight. Moreover, it consumes less power and its performance is much more reliable, being not affected by voltage changed during the car operating. This HID helps to improve the visibility at night, and currently, it is installed only in some newly top-grade car. This kind of lamp is filled in Xenon gas with high technology, light up by increasing the voltage from 12V to 23000Vthat activate xenon gas and cause a super high color temperature light arc between two electrodes. Thanks to this, the efficiency and the brightness of the car have been increased 3 times, the life 10 times increased. HID (the revolutionary product for car headlamp in 21st century), will take the place of traditional halogen lamp for car in the coming future!
