Excellent Heat Dissipation Construction
LASFIT 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.

Polarity Free + –
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, ensures a bright, efficient and long-lasting illumination.
