The Diode Dynamics 31mm SMF2 LED bulb in warm white (3000K) is a single direct-replacement for 31mm festoon bulbs commonly used in vanity mirror lights. With two 5050 SMD LEDs per bulb, it upgrades yellowish incandescent lighting to a warmer modern LED tone and delivers roughly 24 lumens of measured output. The SMF2 includes an embedded load resistor and implanted diode for reliability, constant-current circuitry with transient suppression, and molded terminals to maintain a secure fit. Installation is plug-and-play and Diode Dynamics backs the bulb with a three-year replacement warranty.
