The type of HID and halogen bulb are one-to-one correspondence, that is, what type of halogen bulb is originally used. When the HID is modified, it is necessary to use the same model. H series: H1, H3, H4, H6, H7, H8, H9, H10, H11, H13 and so on; 90 series: 9004 (HB1), 9005, 9006, 9007, etc. Number. H4, H13, 9004, and 9007 are the four types of the original halogen bulbs with two tungsten wires, one far light, one near the lamp, and a xenon lamp that does not do near light and far light in a lamp, so there are four series, such as H (also known as a single light, only a far light or near light). Under the condition of high temperature and high temperature, it is easy to burn, and the life expectancy is only 250 hours. The HID lamp is illuminating by gas discharge, and there is no tungsten wire, so it is not easy to damage. H4-3, H13-3, 9004-3, 9007-3, and H4-H/L, H13-H/L, 9004-H/L, 9007-H/L xenon lamps are all xenon lamps with far and near light, and H/L is the representative of high and low (High/Low).
