What is a festoon bulb?

A festoon bulb is a type of light bulb that is cylindrical in shape with metal caps on both ends. They are commonly used in automotive lighting applications such as dome lights, map lights, and license plate lights. The 41mm measurement refers to the length of the bulb.

How do I install this LED bulb?

Installation is plug-and-play. Simply remove your existing 41mm festoon bulb and replace it with the Diode Dynamics HP6 LED bulb. The metal terminals should fit snugly in the socket.

What does the warranty cover?

Diode Dynamics backs this bulb with a three-year replacement warranty. If the bulb fails due to a manufacturing defect within that time, it will be replaced. Be sure to keep your proof of purchase.
