How bright are these bulbs?

The Diode Dynamics HP11 LED bulb produces 310 lumens. This should provide more total light output than your factory bulb.

How long will these bulbs last?

This bulb is built with constant-current circuitry and transient suppression. This design should last for years, not months, without flickering or failure. Diode Dynamics backs the HP11 with a three-year replacement warranty.

What does "nonpolar" mean for installation?

A nonpolar design means the bulb will work no matter which direction it's plugged in. This simplifies installation, since you don't have to worry about matching the polarity of the socket.
