How do I install these LED bulbs?

Installation is simple: these are plug-and-play replacements for your factory 28mm festoon bulbs. Just remove the old bulb and plug in the new LED bulb. The durable metal terminals will fit snugly in the socket.

What if I want brighter lights?

These SMF1 LED bulbs provide similar light output to your original 28mm-sized bulb, about 16 lumens. If you are looking to increase output, Diode Dynamics recommends checking out their SMF2 option.

What does the warranty cover?

Diode Dynamics backs these LED bulbs with an industry-leading three-year replacement warranty. This warranty covers any failures or defects.
