Ballast Performance: 1. Accept high voltage input :9-16 volts, applied to market various types of vehicles (including trucks, buses and cars). 2.SMR AMD electronic memory chips: the German ultra-large volume capacity, to digital analysis and storage of memory and a variety of high and low voltage instability in the current message, and to prevent the interference of other electronics, the rectifier through the magnetic treatment, can conversion and voltage in order to protect the function and life HID. 3. Pure aluminum housing: non-shedding, Parti, insulated bond strap, will not affect the start and air-conditioning or other electrical equipment interference sound. 4. Working temperature range (40 ℃ - +105 ℃): the engine room of normality can withstand high temperatures, high temperatures caused by lower Failure probability.
