The Diode Dynamics 28mm SMF1 LED bulb set offers a direct replacement for 28mm festoon bulbs used in many vanity mirror lights, upgrading yellowish incandescent output to a modern warm-white appearance. Each SMF1 uses a single 5050 SMD and delivers about 16 lumens, closely matching factory output while improving color and longevity. Built with constant-current circuitry, transient suppression, embedded load resistor and sturdy terminals, the bulbs install plug-and-play and include a three-year replacement warranty.
