License plate bulbs are used to illuminate the rear license plate on your vehicle. From the factory, the bulbs are incandescent, lighting up in a yellowish color.

Newer luxury cars use LED modules to illuminate the license plate with modern, cool white light. By changing your license plate bulbs to LED, you can easily add this luxury look to your vehicle! 

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

 With low price and easy install, this is one of the best, easiest modifications you can do to improve how your car looks at night.



SMD2: Similarly compact design, with two 5050-size Epistar SMD chips, driven at high power for maximum effective brightness. Outputs at 180 degrees.

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.

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.

Included in your order is TWO BULBS.


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 license plate applications- the other colors are illegal in most areas. Please check your local laws before ordering.

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:

SMD2: Slightly higher brightness than OEM bulbs.
HP3: Much brighter than OEM bulbs. These are bright!
HP5: Nearly triple the brightness of stock OEM bulbs!

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.

  2. Doesn't work in 2018 WRX Review by Seth

    Bought these hoping they would work in my 2018 WRX Limited. Granted the listing only says 15-17, but ordered a dome bulb as well and it worked perfectly. I have no doubt these are great bulbs, just be aware that they don't work for the 2018s.

    P.S. Yes I flipped them and all that good stuff. No dice. :( (Posted on 6/26/17)

  3. Great Review by Brandon

    Exactly what I was looking for. Easy to install. Great light. (Posted on 6/4/17)

  4. Hp3 bulbs Review by Oscar

    Had some OLM bulbs before these One bulb lasted 1yr 2 months the other was just shy of the 2yr mark. Very disappointed in those but these HP3's are great all my other bulbs are from DD and none have failed since I've installed them expecting the same from these. Definitely recommended to anyone looking to get rid of the oem bulbs (Posted on 4/13/17)

  5. Must Have Review by John

    Install took less than 5 min, just pop off plastic clips pull trunk layer back, pop out halogens and replace with the LEDs. Make sure when putting in LED you spread the metal wires on bottom of LED just a bit so they can come in contact with housing. I ordered the Cool White (6000k) HP3 bulbs and I think it is the perfect amount of light. Definitely cleans up the rear end. (Posted on 1/29/17)

  6. Great product! Review by Patrick

    These took about 10 minutes to install and gave my car a much better look! I bought the cool white LED bulbs and they look much better than the OEM yellow bulbs. I highly recommend buying these! (Posted on 1/18/17)

  7. So much cleaner Review by Shane

    2016 Subaru WRX

    I purchased the HP3 - 6000K bulb.

    The back of the car looks so much better now. No more dull lighting. The clean LED light goes perfectly with the LED taillights. Bright and clean, but not annoyingly bright. This is the perfect brightness for a nice, clean accent.

    Install was extremely easy. (Posted on 1/9/17)

  8. Looks great and stands out Review by Akuma

    These bulbs look great on my WRX, much better than the dull OEM bulbs. It's very pleasing to look at and will stand out in the dark. Highly recommended upgrade. (Posted on 12/29/16)

  9. Clean Review by Thomas

    Gives a nice clean, and crisp look to the booty on my cwp wrx. Awesome product!! (Posted on 11/4/16)

  10. Nice added touch. Review by Dustin

    These definitely complete the look of the back of your WRX and the price is hard to beat! (Posted on 9/5/16)

  11. Crisp and clean Review by Matt

  12. License Plate LED Review by S_P_I_N_K

    Perfect fit, Easy Install (Posted on 8/8/16)

  13. Excellent Review by James

    I purchased these as well as the trunk light and couldn't be happier with the color and out put. This is a very inexpensive way to upgrade the performance and looks of your car and I highly recommend them! (Posted on 5/12/16)

  14. Great lights. Really add that OEM LED look. Review by Jordan

    I purchased a pair of these bulbs after not being completely satisfied with a different pair of LED bulbs I had ordered and installed. The other bulbs were way too bright and illuminated a good portion of the road behind the car. Made the lights look like they were aftermarket. These bulbs from DiodeDynamics made the license plate lights look 100% stock LED. They are bright but not super bright. There is no huge illumination of the road behind the car anymore which was the look I was originally going for. I'm 100% satisfied with this purchase and would recommend if you are going for a clean OEM LED look. (Posted on 12/26/15)

  15. Much better looking than stock Review by Fred E

    I purchased the SMD2 diodes for my WRX license plate location and am extremely satisfied with how the license plate looks is illuminated now. The pure white light of the 6000K diodes looks much better than the dull yellow of the stock bulbs. Greatly recommended upgrade! (Posted on 12/21/15)


Level of Difficulty: 1/10

Just unplug your factory bulb, and replace it with the new LED one. It is a direct replacement for your vehicle.

Accessing the bulb itself is quite easy. Usually, it is held in by two tabs, and you can pop it out from the outside of the vehicle. In some cases, you will need to remove a few screws, which are clearly visible. Finally, it may be held by clips from the inside, accessible when you open the hatch or trunk.

If it does not work the first time, try flipping it around in the socket, as all LEDs require the correct polarity.
