Product Features LED lamps are more powerful than traditional halogen energy. The brightness and proximity of the Xenon lamp, but the LED lamps light up without delay, to increase traffic safety. Instant start without strong current surges, which effectively protects the car's battery and improves battery life by more than 30%. Fast cooling, the appearance of the most advanced design, 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, repair probability is very low, compared to HID ballast repair lower than 80%. The heating temperature is low, protecting the car. Xenon 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 failure rate. Automotive LED headlights color temperature balancing. The xenon lamps in the same color to pass, about 6000K.
