194 HP3 Bulb is a direct replacement for any 194 size halogen bulb. 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.



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. The bulb is made up of a quality plastic connector to slide right into the plug, as well as high durability terminals. The LED is wired for 12V operation, the kind found on all vehicles.

Included in your order is ONE BULB.


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

 We strongly recommend Cool White or Warm White for the best visibility.



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 our 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 FAQ guide.

  1. Excellent customer service. Review by Jason

    I had one of these start to flicker after a couple of months. A quick email back and forth was all it took. Three days later I had a replacement back in the vehicle. 3 days to Alaska. Thanks (Posted on 4/24/17)

  2. Great Product Review by 2015 Optima

    Installed without issue above license plate plate. Bright. Make a big difference aesthetics wise on the vehicle. (Posted on 4/17/17)

  3. Excellent Quality & Output Review by JL

    I purchased the HP3 in Warm White for my 2015 Colorado. Light output is noticeably brighter and whiter than stock incandescent. I find these LED's in warm white more comfortable for interior lighting since they are still whiter than stock, but feel less harsh than the cooler temps. Tried 4000K first, but did not like the slightly green colour cast. (Posted on 12/23/16)

  5. Brightest and Most Affordable Review by Adrian

    I'm stoked on my Diode Dynamics bulbs. I've upgraded my 2016 F150 with LED fog lights and license plate illuminators. Now, the whole truck has LED lights and looks awesome. Lights fit into the OEM housings no problem. Been running for about 6 months now, no problems!

  9. Good multipurpose LED bulb Review by TuscaniJay

    I bought one of these in Blue so I could match the back-lighting in my Autometer Voltmeter to my dash and interior lighting. Works great and looks great too. Not too bright, not too weak either. You can use these in side markers, license lamps, or any other 194 socket as well. (Posted on 2/28/16)

  11. LED Sidemarker on my 2011 Nissan Maxima SV Review by Aaron

    The plug and play design allowed me to install these bulbs quickly and easily! It fits perfect with my 6K HID headlights and fogs! Now all I need is to purchase the switchback bulbs for my turn signals and I'll have the clean look I want in the front of my vehicle!! (Posted on 4/10/15)

  12. Great product Review by MOO808

    Installed these HP3 Cool White on my 2015 Subaru Impreza Sport Premium and they look great! Looks very classy now! Good quality with a great price. I ordered these for my license plate too! Very happy customer! (Posted on 4/3/15)

  13. Great all around Review by RK

    Perfect price, perfect output, perfect quality.
    Great value all around.

    Ordered several of these for my Accord.
    They put out a crisp pure white light, no hint of blue like other "ebay bulbs", which are inferior to this HP3.

    This little wedge packs a lot of power and I would definitely purchase again.

    Very easy plug n play. Remove old bulb, and insert in the HP3.
    No need to worry about polarity either! which saves time (Posted on 12/17/14)

  14. perfect amount of light Review by OregonDMAX

    These bulbs are great, not too bright but not too dull, they are extremely crisp and do not create hotspots when used exposed or under a lenses of some kind. I fitted my entire interior with these in the doors, footwells, and even map lights. Use this as a maplight bulb and you will be a azed how well you can see! Great product I wouldn't hesitate to buy more. (Posted on 12/9/14)
