39mm Diode Dynamics SMF2 LED Bulbs (Pair), Cool White (6000K)

The 39mm SMF2 LED bulb serves as a direct replacement for any bulb of 39mm size commonly found in dome lights, door 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, the SMF2 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 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 39 lumens of true measured output, the SMF2 LED provides slightly more light output than your original 39mm-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 the real numbers for comparison.

In addition to vibrant colors of blue, red, green, and amber, the SMF2 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.
