This set of four 28mm SMF2 festoon LED bulbs replaces multiple vanity mirror or interior bulbs with modern LEDs, offering a cool-white option that increases output and instantly modernizes interior lighting. Each unit uses two 5050 SMD LEDs and includes an embedded load resistor and implanted diode for reliability, durable metal terminals to prevent vibration, and plug-and-play fitment for 28mm sockets. True measured output of about 24 lumens per bulb provides a noticeable upgrade over incandescent originals.
