194 HP5 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.



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.

Included in your order is ONE BULB.


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

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

Spectrum No green



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.

  10. 2016 WRX - Trunk Review by Patrick

    What a big difference! HP5 are bright! They light up the whole trunk space. (Posted on 10/20/15)

  11. Fantastic product Review by Squid

    Ordered a complete kit to upgrade the lighting on my 2015 Mustang. Was in my '93 LX convertible and realized that the little mirror lights were really dim and aged looking.
    Grabbed up a couple of LEDs that I had laying around the garage and neither of them worked in this application. Had one of these (from the '15 kit), and it fits and is very bright and clear.
    Well done on this product and will be using these to convert the rest of the lighting in the '93 Mustang as well. (Posted on 6/16/15)

  12. f150 Review by Shane

    i had ordered a Red SMD9 bulb to replace the third brake light on my f150, as it turned out they were out of stock on that bulb so i was contacted by Micheal and he offered to send me this new style bulb at no extra cost and i am very pleased. it has great bright color that regular incandescent bulbs will never match. I could not be happier with the products and service from Diode Dynamics and can't wait to order from them again in the future! (Posted on 3/4/15)
