The 28mm SMF1 LED bulb serves as a direct replacement for any bulb of 28mm size commonly found in vanity mirror lights in many vehicles.
Populated with one 5050-size SMD, the SMF1 upgrades the factory yellowish incandescent bulb to a more modern LED appearance.
Designed with an embedded load resistor and implanted diode, the SMF1 ensures superior reliability.
With durable metal terminals, it fits snugly in the socket, and its lightweight design prevents it from vibrating loose over time.
Unlike other bulbs on the market, this bulb features constant-current circuitry along with transient suppression.
This means the bulb will last for years, not months, without flickering or failure.
Like every Diode Dynamics product, it is backed by an industry-leading three-year replacement warranty.
With 21 lumens of true measured output, the SMF1 LED provides similar light output to your original 28mm-sized bulb.
If you seek to increase output, consider our SMF2 option!
All Diode Dynamics LED lighting is rated with accurate measured lumen figures, not calculations or guesses.
We test the true output in-house and provide you the real numbers for comparison.
In addition to vibrant colors of blue, red, amber, and green, the SMF1 is available in cool white 6000K and warm white 3000K options.
Whether you desire a modern cool white appearance or a traditional warm white color, we have the color to fit your need!
After over a decade in business, Diode Dynamics is the most trusted name in automotive LED lighting.
Unlike every other LED distributor, we manufacture and engineer products ourselves in the United States for high quality and fast time-to-market of the newest and brightest LED technologies.
We pride ourselves on offering only quality LED products that will exceed your expectations.
