Question 2. Why do we need "HID"? Have you ever read "blind driving" stunt? Will not gotten me very nervous for the performers? And when you are driving at night without lights in the road, but the roads are narrow and crooked, will have the feeling of stunts? At this point, if your headlights will be brighter, according farther, then certainly increase traffic safety lot, "HID" is based on traffic safety at night and developed a new generation of headlights. Distinguished by: (1) whether the visual light ball across the electrodes have been a serious loss phenomenon. (2) whether the visual ceramic tube rupture, breakage. (3) whether the mesh wire breakage sight. (4) Are there visual lamp breakage, breakage. (5) whether the visual lamp column fracture breakage. (6) Are there loose tube is not strong visual phenomenon. (7) Are there visual Base fall off phenomenon. (8) Are there visual lamp power cord fall off phenomenon. (9) whether the ball lights visually for cracks or broken phenomenon. Test method: (1) take a good Ballast (Ballast), as the benchmark HID lamps. (2) Prepare a power supply voltage to be adjusted to 13.20V as a test reference voltage. (3) are first of all the wiring properly connected, turn the power on to test whether the bulb lighting. (4) If the power is not turned on lights HID lamps, HID said to be damaged. 7. How to identify and test Ballast (Ballast) to distinguish good and bad ways: (1) whether the visual power lines have been destroyed or damaged group situations. (2) whether the visual line of control group destroyed or damage. (3) whether the visual power lines have been destroyed or damaged set of circumstances. (4) whether the high-pressure cartridge visual line group has been destroyed or damaged and missing plastic case. (5) whether the visual ballast body is destroyed or damaged and missing plastic case. Test method: (1) take a good HID lamps, as a test Ballast (Ballast) benchmark. (2) Prepare a power supply voltage to be adjusted to 13.20V as a test reference voltage. (3) are first of all the wiring properly connected, turn the power on to test whether the bulb lighting. (4) If you can not turn on the power HID lamps lit, it indicates Ballast corrupt. (5) If the power is turned HID lights can be lit, it indicates Ballast can lighting, but need to check how much power the input current to determine whether the normal function of the ballast. Judged on the following basis: * between 3A-5A normal input current range. * Greater than 5A shows the efficiency of the ballast reduced, resulting in improved power consumption, reliability decreases. * Less than 3A shows the efficiency of the ballast reduced reliability is low, may lead to re-light the lamp off the case
