Constant Current Driver: The Carbide Series of LED bulbs from GTR Lighting are built using a state of the art Constant Current Driver inside the bulb. This allows them to be more reliable when used on vehicles that have voltage fluctuations due to electrical system design or fault. 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. This helps the LED bulb last longer than bulbs that don't have this device built in.
