·400% Brighter: H11 LED bulb uses double-sided 2000LUX LED chips. 6500K xenon white provides a clear vision for night driving, earlier detecting obstacles ahead, maximizing the driver's reaction time

·Safer Light Pattern: 0.04-inch ultra-thin board design improves light concentration, no shadows or glare, without blinding other drivers to ensures absolute safety for you and oncoming drivers

·1.5X Cooling Efficiency: The aviation aluminum body and a 12,000 RPM turbo cooling fan can reduce the core temperature to below 220F, which avoids lights going out during night driving

·20 Years Lifespan: The lifespan of the best halogen LED bulbs is 1.800 2.000 hours, while SEALIGHT L2 H11 LED lasts over 50,000 hours, which takes the hassle out of frequent bulbs changes

·Instant Illumination: The latest CSP LED chip technology and superconducting copper substrate reduce response time to 10 nanoseconds. Respond to unexpected situations in time to flash the light to remind oncoming drivers to switch low beam

No spots: with its 360-degree light output radius, these bulbs remove all dark spots and provide a much wider angle of output than with standard bulbs.

Prevents blinding on-coming vehicles: these light bulbs utilize the super high quality and most modern technology LED chips. This technology helps you get a LED array similar to the filament inside of an original halogen bulb. This creates a nice cut line on top of beam.

No pain of replacing bulb often: a maximum level of heat dissipation is achieved when they are in use thanks to the ball-bearing cooling fan, the copper thermal heat sink and high-density aluminum body, ensuring headlights up to 50,000 hrs lifespan.

Simple installation: its been designed as a plug and play lighting solution, so does not need the help of a mechanic to fit into most cars.

1 MM ultra-thin design realizes 360-degree illumination. No spots, no shadows--better visibility and greater reflectivity.

IP67 rated ensures SEALIGHT L2 LED headlight bulbs to work well in heavy fog, snow, rain and other bad weather.

Efficient active cooling system with 10,000 RPM Turbo cool silent fan, which achieves the best balance between driving performance and lifespan.
