HID xenon lamp inject xenon into the quartz tubewith high-tech, and then improve the 12 volts power instantaneous increase to 23,000 voltsthrough the precision ballast to stimulate the xenon electrons in the tube to format a strong arc tocontinuouslylightign between the two electrodes, not only more bright, but also more widely, which we called gas discharge.Due to xenon produced by super white arc light similar to the sun in the day, it is definitely the best partner for your driving lighting.
