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.

  1. Awesome Review by David

    Bright light and it makes a big difference in appearance of the car. (Posted on 7/17/17)

  2. Easy Upgrade Review by TriniFL

    The replacement was easy, the difference was amazing. This is a major change if you still have the older bulbs in use. These diodes produce a cleaner, brighter and more visually appealing light. Cannot go wrong... (Posted on 12/20/16)

  3. Outstanding Review by Robjan39

    These LED lights are awesome!!! I am completely satisfied and it changed to look of my new 2016 Kia Optima SXL. Will be a long term customer for sure. (Posted on 11/29/16)

  4. Great Lights Review by Louis

    5 months into owning them and still great.
    Stage 1 was bright enough for me.
    Install was a breeze no problem at all.
    DDs instructions were indeed very helpful.
    Still digging them. (Posted on 4/3/14)

  5. Huge Upgrade, Small Price Review by Nick (North Texas KDM)

    These bulbs add a very nice touch to the back of any car. I went with stage 2, they blend in well and add extra light without being over powering. A very noticeable upgrade for a very low price! (Posted on 8/15/13)

  6. Good Quality, FAST Shipping Review by Nick

    I ordered these on a Monday afternoon and they were here by Thursday. Very fast shipping!

    I went with the stage 2 lights for my license plate. They are slightly brighter than stock without being over powering. They give the back if the car a much classier look. The clean white light looks great with my white car and black/white plate. (Posted on 7/20/13)

  7. Excellent Review by Rock

    These little bulbs made my car look great. Overall quality is superb and installation was super easy. Definitely get these bulbs its worth the few dollars. (Posted on 7/6/13)

  8. Awesome Product Review by Dan

    I ordered the stage 3 and they are amazingly bright. I can see the reflection off the ground from inside the car from them. Super friendly support team and fast shipping. Will be doing business again with Diode very shortly (Posted on 4/6/13)

  9. BRIGHT Review by Jared

    I got the Stage 3. They are better than expected and they shipped the SAME DAY. Very pleased with them and I would recommend them to anyone looking for LEDs (Posted on 3/2/13)

  10. Awesome Review by Big Rob

    I order these to replace my stock license plate lights and I couldn't be more happier. After reading the comments I ordered the White LEDs Stage 2 and the brightness was perfect. Next up on the list is to order new fog light LEDs, and front/back turn signal LEDs. (Posted on 1/22/13)

  11. Love the license plate LED's! Review by Glenn

    I bought the stage 2. These are bright white!

    Before I knew about this site, I would Ebay purchase; only to find I was always unhappy.

    These LED's are by far the BEST!

    Also look up the HID headlights and foglights for your Optima, you will love them! (Posted on 12/15/12)

  12. Very nice! Review by Daniel

    I went with the white stage 2 brightness going by other reviews on here and was not disappointed! They really are much brighter than the factory bulbs and really classy up the car. Highly recommend them. (Posted on 11/24/12)

  13. Excellent Review by Jonathon

    Went with stage 2 and they are the perfect brightness. Highly recommend. A++++ (Posted on 11/7/12)

  14. Very bright and white! Review by Justin

    I bought Stage 2 for my license plate lights and Stage 3 for my front dome lights.

    All I can say is they are awesome. A bright white glow from the front, I took the recommendation of reviewer that said stage 3 would be better in the front.

    The license plate at stage 2 is perfect in my opinion. It does not drown out the color of the plate (white in Maryland) and lights it up nicely. It matches the front of my car now with the HID kit. (Posted on 9/26/12)

  15. Bright and good price! Review by Adam

    I ordered the Stage 2 License Plate LEDs for my 2012 Kia Optima SX and they are great! The bright white LED light emanating from the back of my car really classes it up and makes it look more expensive like a Lexus or something. These lights are way brighter than stock and give the back a crisp look.

    I also ordered a second pair for my interior front dome lights and they are good but a little too dim for my tastes. The stage 2 is definitely brighter than stock but I should've went with the stage 3s for the interior. (Posted on 9/7/12)


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.
