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.

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!
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.

    This lights up my trunk so much more. I have stage 2 so i can't imagine what three or the LED strip are like. This is a great bulb, totally worth the buy. (Posted on 3/16/14)

  7. Looks great Review by Jason

    first things first I purchased this with some other lights and they where so much easier to install. this one gave me a run for my money. The way my trunk light is designed i had to modify some thing to make it fit but it looks amazing. Still would recommend this to anybody they have some of the best light and for a reasonable price considering you get what you pay for. (Posted on 8/14/13)

  8. Great upgrade Review by Enos79

    The stock trunk light was pitiful, but this stage II white LED worked like a charm! Perfect! (Posted on 5/18/13)

  9. Worth Buying Review by OMolina3

    I bought the red stage 4 flexlight. Although the first time I received it I was shipped a green one, I contacted customer service and they replaced it quickly and free of charge. stage 4 is very bright and worth every penny I spent on it. (Posted on 3/18/13)

  10. Great color,price and brightness Review by Chris

    Got the blue led in the trunk of my red koup and im loving the color and its just the right brightness. Gives my trunk a nice look. (Posted on 2/21/13)

  11. Stage 3 Review by Koup

    The red, stage 3 option has a great color output, but I kinda wish it was a little brighter. Gives my trunk a really nice look overall tho. (Posted on 2/15/13)

  12. Very Bright Light Review by James

    Purchased the Stage 3... it really lights up the trunk quite nicely. This is the way the car should have come directly from the factory! (Posted on 1/6/13)

  13. Great replacement Led light Review by Reed

    I bought the stage 4 flex light in red it is way brighter than the factory light and was a great price. DD is the best company out there and as always very fast shipping and has great customer service!!! (Posted on 10/30/12)

  14. Not the Greatest Design, But Does What's Advertised Review by DrPhil

    Unless you like the plastic lens to bow out, the circuit board/led unit doesn't actually fit properly on the lens, unless you get creative with a rotary tool. The connections had to be tweaked using needle-nose pliers in order to allow the festoon-tipped bulb adapter to fit (and stay) between the contact points. Stage 3 white obtained for the trunk area and it is VERY bright. (Posted on 10/25/12)
