Xenon lamp xenon lamp types by bulbs of models, and can be divided into three series, namely 900 series, H series, D series and 8 series, 900 series have 9004 \ 9005 \ 9006 \ 9007, H Series There H1 \ H3 \ H4 \ H7 \ H8 \ H9 \ H10 \ H11 \ H13, D series have D1 \ D2 \ D4, 8 series 880 \ 881. Ordinary headlight bulbs these models and car models are corresponding; there is a reconfiguration of car headlights, is called with a lens \ with angel eyes, which is a modified xenon lights, headlight lens is The condenser of the good, but a modified headlight seal is not good, the angel eyes play a decorative effect is not practical. In Europe, the use of xenon bulbs must use quality standards and meet the requirements of the lens and headlight cleaning system, doing so is to prevent the formation of improper use xenon headlights for safety hazards caused by traffic. And no relevant domestic laws and regulations, but still recommended in the modified xenon headlights with at least the appropriate lens, and the corresponding debugging. Classification of HID and halogen bulbs HID model is one to one, that is what the original halogen bulb model, then converted HID time, also need to use the same model. HID currently divided by the Base Model: H series: H1, H3, H3C, H4, H6 (single claw PH7, jaw PH8), H7, H8, H9, H10, H11, H13, etc.; 90 Series: 9004 (HB1) , 9005 (HB3), 9006 (HB4), 9007 (HB5), etc.; D series: D1S, D1C, D1R, D2R, D1C, D2C, D3C, D4C, etc.; 8 Series: 880, 881 in many applications in the automotive HID the H1, H4, H7, 9005,9006 and other models. H4, H13, 9004,9007 these four models, the original halogen bulb which has two tungsten wire, a far light, one is near the lamp, and as xenon lamp in a lamp inside nearly impossible light beam, so there were four series, such as: H (also known as single lamp, but also real-time or near-light beam only), lower temperature heat, easy to blow, the average life expectancy is only 250 hours; HID lamps using gas discharge light, no tungsten present, difficult to damage. H4-1 (H4 / L), H13-1 (H13 / L) ,9004-1 (9004 / L) ,9007-1 (9007 / L); H4-2 (H4 / H), H13-2 (H13 / H) ,9004-2 (9004 / H) ,9007-2 (9007 / H); H4-3 (H4 H / L), H13-3 (H13 H / L) ,9004-3 (9004 H / L ) ,9007-3 (9007 H / L) Model distance light xenon lights are one of the xenon lamp; where L is the low light of representatives (Low), H is the high light of representatives (High), H / L is low lights representatives (High / Low)
