The 28mm SMF2 red bulb pair replaces common 28mm festoon incandescent bulbs in vanity mirrors and interior lamps with modern LEDs and improved output. Each unit uses two 5050 SMD LEDs and includes an embedded load resistor and implanted diode for enhanced reliability, plus sturdy metal terminals to ensure a secure fit. At about 24 lumens measured output per bulb, the SMF2 pair offers plug-and-play installation and a reliable, longer-lasting interior lighting upgrade.
