The Diode Dynamics 31mm SMF2 LED bulb in red is sold as a pair and replaces factory 31mm festoon bulbs commonly used in vanity mirror lights. Each bulb uses two 5050 SMD LEDs to provide about 24 lumens of measured output, improving brightness while delivering a modern red appearance. The design incorporates an embedded load resistor and implanted diode, constant-current circuitry with transient suppression, and molded terminals for a snug fit that resists vibration. Installation is plug-and-play and the pair carries a three-year replacement warranty.
