31mm Diode Dynamics SMF2 LED Bulbs (Single), Warm White (3000K)

The 31mm SMF2 LED bulb serves as a direct replacement for any 31mm-size bulb commonly found in dome lights, map lights, and trunk lights in many vehicles.

Populated with two 5050-size SMDs, the SMF2 upgrades the factory yellowish incandescent bulb to a more modern LED appearance.

Designed with an embedded load resistor and implanted diode, it offers superior reliability.

Its durable metal terminals ensure a snug fit 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, which means it 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 19 lumens of true measured output, the SMF2 LED provides similar light output to your original 31mm-sized bulb.

If you seek to increase output, consider our HP6 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 with real numbers for comparison.

In addition to vibrant colors of blue, red, amber, and green, the SMF2 is available in a cool white 6000K and warm white 3000K option.

Whether you prefer 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.
