What size is this bulb?

This is a 39mm festoon bulb. It's a direct replacement for any 39mm-size bulb, commonly found in vanity mirror lights in many vehicles.

How bright is this bulb?

The SMF2 LED provides 24 lumens of light output, about double the total light compared to your original 39mm-sized bulb. All Diode Dynamics LED lighting is rated with accurate, measured lumen figures.

What if the bulb fails?

This bulb is built with constant-current circuitry, along with transient suppression, so it should last for years. But if it doesn't, it's backed by a three-year replacement warranty from Diode Dynamics.
