What is a festoon bulb?

A festoon bulb is a type of automotive light bulb that is cylindrical in shape with metal caps on both ends. They are commonly used for interior lighting applications such as dome lights, map lights, and trunk lights.

What color temperature is this LED bulb?

This Diode Dynamics HP6 LED bulb is the cool white 6000K option. This provides a modern, clean white appearance, without the yellowish tint of a standard incandescent bulb.

What if the bulb flickers or fails?

This bulb is built with constant-current circuitry and transient suppression, so it should last for years. But if it does fail, it's backed by a three-year replacement warranty from Diode Dynamics.
