31mm LED Bulbs
Typically serving as a map, dome, or trunk light bulb, the 31mm size bulb is easily upgradable in most modern vehicles. Diode Dynamics currently offers plug-and-play LED upgrade bulbs in the 31mm size that drop right into place of stock incandescent bulbs! Our LED replacements are brighter, more reliable, and come in a variety of colors.
