Trunk lights are used in the trunk or cargo area to illuminate the space at night. From the factory, the bulbs are incandescent, lighting up in a yellowish color.

By changing the factory bulb to an LED, you can illuminate the area with a much brighter light, and add a pure white, luxury look.

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. 

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

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. This may need to be mounted to the exterior of your trunk light housing.

FlexLight: This is a 20-inch, low-profile LED strip, with 30 5050-size Epistar SMD chips. Comes with spring-loaded festoon-style adapter for direct installation. Mounts in your trunk area, flexible and waterproof, for maximum brightness.

Fitment. All bulbs use a standard 31mm terminal, with aluminum contacts, designed for exact replacement of your factory 31mm festoon bulb. Just remove the old bulb, and plug in the new LED.

PLEASE NOTE: SMD12 Board is an LED board, which may mount to the exterior of your trunk light housing. FlexLight is an LED strip, which plugs into your factory trunk light socket, and mounts directly into your trunk area using included adhesive strips or velcro. If you would like a direct replacement bulb, we recommend SMF2 or SMF6. We offer SMD12 Board and FlexLight for those who want to maximize brightness.

Included in your order is ONE BULB.


These LEDs are available in crisp, bright colors including White, Warm White, Blue, Red, Amber, and Green.

 We strongly recommend white or warm white for the best visibility.

Color Reference Banner


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.
SMF4: Slightly higher brightness than OEM bulbs.
SMD12 Board: Much brighter than OEM bulbs. These are bright!
FlexLight: Extremely bright compared to OEM bulb.

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. Quality Stuff! Review by nvsty_302

    Very bright, so much better than the stock bulb. (Posted on 7/17/17)

  2. Fantastic trunk light Review by Glenn D.

    I echo a previous review. If you're tired of the yellowish glow in your trunk from the OEM incandescent bulb and can't find anything at night in it then you need to make the change to this LED bulb. Due to enclosed space and having luggage or other items in the trunk I bought the highest lumen rated bulb and couldn't be happier! (Posted on 5/8/17)

  3. Amazing quality Review by Connorconnor

    These lights have a perfect OEM fit with outstanding quality! Really helps light up your entire trunk! (Posted on 12/11/16)

  4. SMD12 - Very bright, easy install Review by Andre

    I ordered the SMD12 board, which isn't just a direct plug in, but is still very easy to install.

    One thing to note is to be careful when removing the old trunk light, I somehow managed to blow a fuse while getting the old one out, but that was likely just me being careless. Other than that, install was easy and the board is WAY brighter than the stock POS. (Posted on 8/22/16)

  5. Great LED Review by Chris

    Awesome product. Can actually see in the trunk now at night. Installation is a breeze. Highly recommend. (Posted on 6/18/16)

  6. Amazing trunk LED bulbs!! Review by JR

    Overall, this Cool White 6K SMF4 LED bulb is perfect! The bulb definitely brightens up the trunk all while providing a nice clean, white output. If you want to clean up the interior, be sure to get the matching SMF4 bulbs and I know you'll enjoy them as much as I do. To be honest, with this bulb, the Mustang feels premium again since Ford's bulb mainly have a yellow tint to them and this cool white bulb is perfect! (Posted on 1/10/16)

  7. Great Light Output Review by Korey

    This bulb is a 100% improvement over the stock yellowish halogen bulb. It is super crisp, clean and bright, I purchased the 6000k SMF4 bulbs and they are fantastic, especially at night. I would highly recommend these to anyone who is looking for great output, improved appearance, a great price and great quality. (Posted on 12/14/15)

  8. Amazing Review by Ethan

    Great light output and prefict crisp white color! (Posted on 10/31/15)

  9. Great Price and Value Review by Jon

    This is a bright little light which still fits in the factory slot. Well worth the buy. Would definitely be interested to see how bright the larger LEDs are in person! (Posted on 10/2/15)

  10. Great! Review by Jason

    Got the stage 2 for my trunk and it's nice a bright! A bit brighter than stock, but a nice pure white. Maybe someday I'll go for a colored LED; that would probably look cool..but in terms of needing some light at night, the white LED looks great! (Posted on 6/30/15)

  11. Very Bright! Would definitely recommend stage two bulbs Review by Kyle

    These bulbs are a huge change from the ugly incandescent yellow light that Ford puts in the trunk! I would def recommend getting the stage two bulb though it is very bright and not much more price wise. I feel like the stage one bulb wouldn't quite be enough light. Adds so much more light and looks so much better! (Posted on 1/20/15)

  12. Trunk Light Review by Dan S

    All I can Say is (Wow) what a difference, compared to the OEM bulb, this is a 100% improvement.
    I wish I would have known about your company years ago, your products are 1st class. Very impressed.

  13. Amazing Review by Konagt

    Truck light is a lot brighter now ..... Product lights up great at night for better visibility (Posted on 1/12/14)

  14. I'm happy with it Review by Greg

    I would sugest to get the Stage 2 for sure. I know stage 3 is more of a ciruit board and I'm not sure if it would fit. I may give it a try. But for now the Stage 2 works great. It gives off a nice white light and looks way better than stock. I put this in my 2011 mustang GT (yellow) I also uploaded a photo. (Posted on 12/13/13)

  15. Much Better Review by Jeff

    I needed a little more light in the trunk. Stage 2 white gets the job done and fits in the factory socket. The white is crisp and better than the yellowish factory bulbs. (Posted on 11/20/13)

  16. Perfect Review by Mike C

    My wife's light went out so I bought her one of these. Works great. This product is simply perfect. (Posted on 8/20/13)

  17. Very cool! Review by Michael

    I got the stage 2 blue for my trunk and it is awesome! Very bright despite the dark hue of blue and i love to show my friends at night! Definitely recommending to everyone i can! (Posted on 7/23/13)

  18. What an upgrade! Review by Cristoff

    I found these on a Mustang Forum after looking long and hard for lighting to match the Black / Green color theme of my car. These lights are simply amazing! Several times brighter than stock, but more importantly, a much more "pure" light. The Green is very vibrant, and the quality of the product appears to be top notch. I had no idea how dim the factory trunk light was until I put in the LEDs. Easy to install and OH SO WORTH IT! (Posted on 4/26/13)

  19. Great LED value Review by Doug

    I've tried other more costly LEDs in the past, and to date, nothing beats the quality of these LEDs. Perfect fitment, no issues. (Posted on 4/5/13)
