What does "warm white" look like?

The warm white option has a color temperature of 3000K. This provides a traditional incandescent look, similar to the original bulbs in many vehicles, but with the benefits of LED technology.

How do I install these LED bulbs?

Installation is plug-and-play. Simply remove the factory bulb and replace it with the Diode Dynamics SMF2 LED bulb. The metal terminals should fit snugly in the socket.

What if the bulb fails?

These bulbs are built with constant-current circuitry and transient suppression for long life. However, if you experience any issues, Diode Dynamics backs these bulbs with a 3-year replacement warranty.
