What is a festoon bulb?

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

What does 'constant-current circuitry' mean for the bulb?

Constant-current circuitry regulates the current flowing through the LEDs, ensuring consistent brightness and preventing damage from voltage fluctuations. This design choice helps the bulb last longer without flickering or premature failure.

Are these bulbs sold individually or as a pair?

This product includes two bulbs, so you can replace a pair of lights at once. Replacing bulbs in pairs ensures consistent color and brightness.
