Your dome light, or single light located in the center of the ceiling, uses an incandescent bulb from the factory, giving it a yellowish color. By replacing with an LED, you can add a luxurious and modern look to your vehicle, with a cool white color, just like the lights on newer luxury vehicles. You can also increase the brightness with SMF6 or SMD12 Board, to improve the performance of your dome light.

The installation is 100% plug-and-play, just replace your factory bulb!



SMF2: This bulb has a standard festoon base, with two 5050-size Epistar SMDs and a protective cover for added durability and style. Direct replacement, plug and play.

SMF6: Standard festoon base, with six 5050-size Epistar SMD chips arranged on a rectangular panel. Direct replacement, plug and play.

SMD12 Board: This is an LED panel, fitted with 12 5050-size Epistar SMD chips. Comes with spring-loaded festoon-style adapter for direct installation. Plug the adapter into the bulb socket, then just stick the board in place with the mounting adhesive pad. The board-and-adapter design allows for extremely high brightness compared to a simple bulb.

Included in your order is ONE BULB.


These LEDs are available in many crisp, bright colors. White and warm white are the most popular colors, for a modern look with maximum visible light.

You can also select blue, red, green, or amber to add a unique look to your interior. Please note- when ordering these unique colors, we recommend moving to the next-brighter stage for acceptable light output.

Diode Dynamics offers several brightness options so you can choose what fits you best.  These options are listed by the design and the lumen output of each bulb: 

SMF2: Slightly lower brightness than OEM bulbs, but still provides the crisp, modern color of LED.
SMF6: Slightly higher brightness than OEM bulbs.
SMD12 Board: Much brighter than OEM bulbs. These are bright!

Lumens: BUYER BEWARE! Most sellers just provide "calculated" lumen numbers, based on the maximum potential brightness of the LED chips on the bulb. For example, if a bulb has five 10-lumen chips, they will rate it at 50 lumens. However, this is not accurate, as the design of an LED bulb does not get rid of heat fast enough to run the LEDs at maximum.

These "calculated" lumen ratings are much, much higher than the true, measured light output, so it will look like competitors' bulbs are brighter than ours. This is because Diode Dynamics does not provide inflated "calculated" numbers; we believe it is misleading. We test the actual brightness of the bulbs in our lab, to provide real lumen output measurements. Our measurements are accurate, but they are usually much lower than the misleading "calculated" figures. Please click here to learn more about LED brightness measurement.



LED Components. Diode Dynamics uses only the highest quality LED chips in the production of its bulbs. This means we use only brand-name suppliers such as Epistar, Cree, Osram, and Samsung.

While Diode Dynamics bulbs may look the same as others on the market, most copycat bulbs use economy-grade LED chips in order to reduce costs. This greatly reduces the reliability and overall brightness of the bulb when you compare it to Diode Dynamics.

Construction. Although LED technology allows for extremely long bulb life, the market is flooded with cheap LED bulbs that fail prematurely due to inferior construction. The worst enemy of LEDs is excessive heat, and when bulbs are not designed properly, they do not disperse heat as well, leading to premature failure.

Off-brand, cheap bulbs exhibit poor solder uniformity, high levels of flux in the solder, uneven chip placement, low-gauge terminal wires, poor assembly, and bulbs held together with inferior adhesives. At best, solder joints will crack and fail on low-quality LEDs after a few weeks of use. In the worst case, these bulbs can damage housings as the extra flux and adhesive evaporates and creates a residue on the lens of the housing.

Diode Dynamics bulbs are produced with modern, computerized equipment, and only the best materials, to ensure complete uniformity, high quality, and long bulb life.

All Diode Dynamics products come with a 30-day satisfaction guarantee and a 3-year limited replacement warranty. For more information, please view the Warranty Information page.

  1. Great product, easy install Review by Corey

    2012 Subaru Legacy 3.6R, opted for SMF2 in Cool White. Extremely easy installation, very pleased with color and brightness. Highly recommended. (Posted on 9/20/16)

  2. Nice N Bright Review by Tim

    Way brighter than the OEM bulb, in fact more than enough crispy white light. Very easy to install and were a direct fit. (Posted on 7/2/16)

  3. Very bright and very easy install Review by Chris

    Very inexpensive and very easy to install. I'm not a very hands on guy and I could do this. Hardest part is popping off the covers. A lot brighter than stock bulbs with a variety of colors to choose from. (Posted on 2/23/16)

  4. Excellent product Review by DanC

    The light output is much nicer than the OEM bulb, installation was simple, and the customer service was top-notch. I was so impressed with the dome light, and the map light LEDs, that I ordered the back-up light LEDs too. (Posted on 11/16/15)

  5. LED Dome Light Review by OSIMA

    Best light ever. Now I can see! (Posted on 11/16/15)

  6. Great! Review by Rod

    I ordered this months ago, and it was delivered in time, and installed them on my 05 LGT. It shines so much nicer, and gives it a much nicer modern look to the car. I love the Ice white glow that it gives out, and really nice and easy interior mod. A must do for any vehicle. (Posted on 6/9/15)

  7. LED's Upgrade Review by Spencer

    Cool White (6000K) SMF6 (94 Lumens). Very bright and easy to install. (Posted on 5/21/15)

  8. Cool White SMF6 Review by Verwilderd

    Got the second brightest bulb offered. Simply put, this is a perfect option. Mounts directly in the stock location as if it were a stock bulb and is brighter than the stock bulb. It is not excessively brighter, but certainly makes a difference. I think this was a perfect choice for this application (Posted on 12/7/14)

  9. Awesome product, much brighter and better looking Review by Matthew

    I'm very pleased with my purchase, it has added that premium feel inside the car and added lots more light. Originally, I went with Stage 1, but it was too dim for my liking. Upgraded to Stage 2, couldn't be happier. (Posted on 10/29/14)

  10. Super bright! Review by Scott

    At first I went with the cool white SMF6 for the dome light in my 2014 Subaru Legacy. I was amazed at the output. Don't look directly into the light it will blind you! My Legacy has the black cloth interior so next I wanted to try out the SMD12 Board. The light output of the board is not that much brighter than the SMF6. It was still super bright. Fitment with the board is snug since you have to use the adapter. An awesome product, the price is right, and the LED light has a nice icy white color that looks great. (Posted on 9/22/14)

  11. Awesome product! Review by Jake

    I'm very satisfied with the dome light i received. I purchased a blue SMF6, and it is great! Installation couldn't have been easier, just simply replaced the bulb. I'm satisfied with the brightness of the bulb and for 13 dollars including shipping, it was a steal! (Posted on 5/17/14)

  12. 2012 Legacy LED Upgrade Review by Eric

    I recently purchased and installed the Stage 2 Dome light in my 2012 Subaru Legacy. All I can say is, WOW! What a dramatic change!

    With the old OEM halogen lighting, I couldn't see anything in the car once the sun went down. Now with this new stage 2 dome light (coupled with the Stage 2 Map Lights), I can see everything.

    These quick plug-and-play bulbs are the quickest and cheapest way to dramatically improve the look of your vehicle!

    Personally I wouldn't go brighter than stage 2 because it is perfect for me, but if you are trying to improve your tan, you could always go with stage 3. haha..

    I highly recommend these bulbs and I highly recommend doing business with Diode Dynamics. They were awesome to work with and I will be doing more business with them in the future. (Posted on 3/2/14)

  13. From no light to stage 2: Wow. Review by Stu

    My dome light was burnt out forever, and I would always forget about it when I was bootin around the internet. Then I finally remembered, searched, and came across DD. I saw the price on the dome light and decided to order it and a few other bulbs to try out Diode Dynamics. I was thoroughly impressed. After almost a year without my dome light, the Stage 2 is insane. I absolutely love how bright and white it is. I am getting away from the OEM bulbs and their yellowy white hue and so far all the LEDs I have bought from DD have been great price, very easy install with only a small screwdriver to pop off lens covers, and the results are great. I and a few friends will definitely order more bulbs from here. (Posted on 10/20/13)

  14. Excellent light output for passengers Review by Steve

    Bought the Stg2 (white) as part of the whole interior LED revamp in my 08 LGT. The lights look great, and even at Stg2, it's bright enough to provide solid illumination throughout the car's interior. (Posted on 9/24/13)

  15. Amazing Review by Charlie

    I went with the stage 3 all around in my wagon and they make up for the poor light placement by Subaru. I could finally see in the front without having to turn on my map lights. If anyone has a 2005 Legacy wagon with a sun roof this will make a huge difference with the lighting. (Posted on 5/24/13)

  16. Awesome Light! Review by Jon

    I paired this, stage 2, dome light with the stage 2 map lights and WOW! This light is so much better than stock! (Posted on 4/16/13)

  17. Good but Fitment Review by Shyun

    These seem like they are very high quality however fitment was a bit finicky. Just a heads up that bending was required for install. (Posted on 1/15/13)

  18. Excellent Product! Review by Justin

    Went from a dead dome light to the stage 2 white kit and couldn't be happier! Paired with the rest of the stage 2 white LEDs for the interior - I'm really pleased with the results and I highly recommend the upgrade! (Posted on 11/20/12)
