How do I install these LED bulbs?

Installation is plug-and-play. Simply remove the old 28mm festoon bulb from your vanity mirror light socket and replace it with the Diode Dynamics SMF1 LED bulb. The metal terminals are designed to fit snugly in the socket.

What is the color temperature of these LED bulbs?

These SMF1 LED bulbs are the 'warm white' option, which has a color temperature of 3000K. This provides a traditional warm white color, similar to the original incandescent bulb, but with a more modern appearance.

What if I want a brighter light output?

These SMF1 LED bulbs provide 16 lumens of light output, similar to your original 28mm bulb. If you want increased output, Diode Dynamics recommends their SMF2 option.
