Product features LED lamps compared to traditional halogen energy, more power. The brightness and proximity of the xenon lamp, but LED lamps light up without delay, to improve traffic safety. Instant start without strong current, effectively protects the car supplied with a battery, improves battery life by more than 30%. Fast cooling, the most advanced appearance, thermal structure ingenious and reasonable. Less warranty, power driver with wide voltage constant current mode, the car can respond to a variety of voltage instabilities, the effective protection of normal use Led efficient and simple structure. Fewer components damaged, the probability of repair is very low, compared to HID ballast repair lower than 80%. The heating temperature is low, protects the car. Xenon's operating temperature up to 800 -1000, the main cause of car ignition. LED car headlights simple structure, fewer parts than xenon lamps, significantly lower than the xenon lamp's failure rate. Car LED headlights color temperature balancing. The xenon lamps in the same color to clear, about 6000K.
