• A Higher Level of Visibility: Using high power 7535 SMD + 1860 SMD chips to produce peak brightness output, and less heat compared to other bulbs that sometimes use up to 30 chips, 360 degree illumination with no blind spot and shadow Make a big difference for your vehicle!
• Excellent Heat Dissipation Construction: The bulbs use built of lightweight and high-strength aluminum alloy as bulb body to keep themselves cool, even if they're used in constant-on applications like daytime running lights, they still illuminate non-fading brightness. Some bulbs, which were covered in many LED chips will haven't enough cooling surfaces.
• Non-Polarity Design + - : You needn't worry whether you have a CK or Non-CK socket, these bulbs are universally compatible. They will fit into the same socket as your OEM original bulbs,No electromagnetic interference,No need to consider polarity while installing, 1 inch design makes sizing comparable to halogen bulbs, fit perfectly in your vehicle. Truly plug & play
• Built-in Constant Current IC Driver：A constant current driver is a device that takes any incoming voltage and smooths it out, regulates it, so a steady stream of voltage/current reaches the LED, ensures a bright, efficient and long-lasting illumination,and prevent the bulb from burning out when the voltage is unstable.
