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.



HP3: One high-power SMD under a diffusing lens for truly even output (no hotspots). Constant current design and air-cooled base for superior reliability. Features dual contact pins and nonpolar function for easy installation.

HP5: Four high-power SMDs, under a diffusing lens. Just like the HP3, but run at higher power, with integrated copper plating for superior heat dissipation, allowing maximum brightness.

SMD12 Board: This is an LED panel, fitted with 12 5050-size Epistar SMD chips. Comes with wedge-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 wedge-style adapter for direct installation. Mounts in your trunk area, flexible and waterproof, for maximum brightness.

Fitment. All bulbs use a quality inject-molded 194/168 T10 terminal, with a full-size base connector and proper pin alignment, designed for exact replacement of your factory 194 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 SMD5 or SMD9. 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:

HP3: Slightly lower brightness than OEM bulbs, but still provides the crisp, modern color of LED.
HP5: Nearly triple the brightness of stock 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. Need to get! Review by Dustin

    This bulb blows the stock trunk light out of the water. You can actually see everything in your trunk at night vs stock. Need to buy! (Posted on 9/5/16)

  2. love the looks Review by Matt

    Crisp clean light now. (Posted on 8/31/16)

  3. Flexlight super bright!!! Review by Alex

    Installment wasn't difficult coming from a guy with little car experience and once I got the product installed I could tell a huge difference right away. This led strip literally lights up the entire trunk at night and gives off a nice white light. Definitely an easy and cost effective way to brighten up your trunk and give it that wow factor. (Posted on 7/2/16)

  4. Very clean Review by Eric

    I purchased the HP5W while converting all interior lights to LED in my 2016 STI. I went with this build as I wanted a direct fit, and did not want to mount an LED board. The colour is great and brighter than stock. Shipping was fast and lights were packaged nicely. Very happy with my order. (Posted on 6/18/16)

  5. Looks Great! Review by Josh

    Pain to remove the cover but once it's off it looks awesome!!! (Posted on 5/15/16)

  6. Excellent Review by James

    I bought this as well as the license plate lights and I'm very pleased with them. Excellent quality, fit and installation was simple with no errors. The color is great and a lot brighter. Highly recommend these for a inexpensive upgrade and improve the of looks and performance! (Posted on 5/12/16)

  7. Flexlight for the trunk Review by P C

    The Flexlight for the trunk is an exceptional value. With the stock bulb, nothing can be seen unless I am outdoor in the sunlight. With the Flexlight installed, everything can be seen in the trunk even in a dark garage. I had to make a slight adjustment to the end of the plug to make the plug stay in better. Overall, I am satisfied with the Flexlight. (Posted on 5/2/16)

  8. HP5 vs. FlexLight Review by PCHone

    I purchased both the HP5 bulb and the FlexLight in 6000K and was surprised I liked the HP5 bulb. The HP5 had much higher output than stock and I stuck with it. I tested out the SMD-12 bulb (same as dome light bulb) and the FlexLight and while they were brighter, I did not find them aesthetically pleasing since they both would have to be mounted outside the factory housing. The HP5 was more than sufficient and couple of my friends said they wished their trunk lights was as bright as mine.

    As always, DD's 3 year warranty is a plus! (Posted on 3/23/16)

  9. Awesome Product! Review by Ethan

    Very easy install. Comes with everything you will need. I bought the 200 Lumen strip light and it looks Great! (Posted on 3/11/16)

  10. Great upgrade as usual Review by Fred E

    I bought and installed the HP5 diode in 6000K for my WRX trunk and it's amazing upgrade. The installation was incredibly simple and I was admiring the increase in light quality in less than 5 minutes. The bright white from this diode is much better than the dull yellow of the stock bulb and illuminates every corner of the trunk. Greatly recommended purchase! (Posted on 12/21/15)

  11. Great look Review by Tim

    Once installed and checking them out at night they look awesome they lit up the trunk perfect. I got the blue strip was super easy to install. I had one problem and that was with the connection it seemed kinda cheaply made it kept flickering when I touched the wires. After messing with it for awhile it stopped but was a pain. But great look! (Posted on 12/14/15)

  12. Big Improvement Review by Ranelle

    Installed in 2016 Subaru WRX and what a big improvement in the trunk. Completely plug and play. Excellent customer service, all my concern where answered and will surely check other items for my 2016 Subaru WRX. (Posted on 8/18/15)

  13. Big Improvement Review by Hayward

    Installed in my 2016 Subaru WRX and made a big improvement definitely worth it. Excellent customer service all my issue where answered Highly recommended and will check other product for sure. (Posted on 8/18/15)

  14. Excellent Review by Ryan

    This little light bulb rocks! I recommend spending the extra $4 for the HP5 model. Plenty of light for the trunk area, and the cool white color is very modern. (Posted on 8/14/15)

  15. Huge upgrade Review by Ken

    Well, a single 192 bulb in a large area of your trunk is the LAST place you want low level light especially if you're back there with a flat tire or simply need to load or unload cargo. Upgraded to the HP5, and although fitment was tight, the light output was about triple. Additionally, it fits back into the OEM plastic shroud.

    Don't think about it, get it! (Posted on 5/20/15)

  16. A necessary upgrade. Review by Jeff

    I purchased and installed the HP5 6000K version of the trunk light. Quite a huge difference between the dull yellowish glow from stock to the bright white illumination produced by the HP5. Coverage of light is also much larger as this light is far brighter than stock. Fits right in under the plastic diffuser perfectly. This is a fantastic upgrade as you can see everything in your trunk clearly at night. (Posted on 4/14/15)
