H13 led headlight bulb 1. BETTER VISIBILITY - Lightening dark H13 led headlight bulbs adopt customized high efficient CREE LEDs array. The Lumens output is 10,000 Lumens (5,000lms per bulb), 170% Higher than the industry level. High focus, more light, wider and farther lighting area, Safer Night Driving! Cool white 6,000K lighting - No dark spot, No foggy light. 2. PERFECT ALIGNMENT - Optically engineered to mimic halogen filament for accurately focused light output. The precise placement of the LED chips results in a perfect beam pattern every single time. 3. THERMAL ANALYSIS - Advanced thermal analysis technology limits the critical temperature of the LEDs. Using the copper with outstanding thermal conductivity as original plate, which makes the heat from LEDs transmit quickly to the high power fan. 4. EASY INSTALLATION - All in One Design.Plug and Play. NO relay, NO capacitor, Zero seconds fast start. Average Installation time is within 20mins. IP67-rated water resistant and designed for use in heavy rains. Rainproof driver, housing, and fan work even in extreme situations. 5. LONGER LIFESPAN - Powered by Intelligent Output Technology for fined tuned power output. Enhanced light efficiency with higher optical density and lower heat resistance. Advanced LED chip with new Turbo Fan provides over 50,000 hours of brilliant continuous light.
