The Diode Dynamics 39mm SMF2 LED bulb in warm white, sold as a pair, replaces factory 39mm festoon bulbs in vanity mirror and interior lighting. Each unit uses two 5050 SMDs to provide a measured 24 lumens and a warm LED tone with greater output than many stock festoons. Embedded load resistor and implanted diode enhance reliability, while constant-current circuitry and transient suppression ensure stable, plug-and-play performance with a three-year replacement warranty.
