LASFIT L Series bulbs have an impressively bright, pure white, sharp light output with a gorgeous metal style. It's easy to upgrade the factory yellowish bulb to LED. These high-performance bulbs will not only help improve visibility, but will create a high-end look making your car stand out. -Key Feature- A Higher Level of Visibility Using high power 3030 SMD LED chips, just 10 chips per bulb to produce peak brightness output, and less heat compared to other bulbs that sometimes use up to 30 chips. Make a big difference for your vehicle! Excellent Heat Dissipation Construction LASFIT bulbs are 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.  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, ensuring a bright, efficient and long-lasting illumination.
