Features: The product uses high-power chips, and the ultra-thin board shape design makes the installation and fit better, and the illumination is more uniform, avoiding the disadvantages of poor illumination width caused by the point light source. This SMD product has the characteristics of light diffusivity, wide-angle illumination and high lumen. There is no delay in lighting, high light purity, strong color rendering and penetrating power; LED light-emitting diodes are used, power consumption is small, and automotive circuits can be better protected. LED has no filament, good heat dissipation, low current, low heat generation, and the vehicle circuit is not easy to oxidize. Long Lifespan, canbus error free, aluminum heat dissipation, extremely bright with constant current, Non-Polarity design,Plug and for play. With strong shock resistance and low temperature rise, it is a new generation of revolutionary solid-state light source.
