HP36: Full 360 degree illumination with 36 High-Power Samsung LEDs. Aluminum base for optimum heatsinking, and non-polar design for easy installation.
XP50: Each of the four sides of this bulb contains two 5W-rated chips, and the top is fitted with two more under a projector lens. Housed in an aluminum casing with textured finish for maximum heatsinking properties.
Fitment. All three bulbs use a quality inject-molded 921 terminal, with a sturdy base connector and proper pin alignment, designed for exact replacement of your factory 921 bulb. You will not need resistors for backup lights. Just replace the factory bulb.
Included in your order is TWO BULBS.
These LEDs illuminate in a crisp, cool, bright, white hue for maximum light output.
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:
HP36: Slightly higher brightness than OEM bulbs.
XP50: Much brighter than OEM bulbs. These are bright!
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, 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.

Awesome product, but.... Review by A Montero
Price Value Quality
First off, for my 2004 Silverado, I needed a resistor to get it to work. Without it, lights were dim. Resistor I used was a 390 ohm x 2w. Other than that, bulbs shipped fast, and customer service was willing to exchange or accept my return. Customer service replied in a timely manner through email and was fre=iendly and helpful as can be. (Posted on 10/16/16)

I bought the xp50 bulbs for my 2015 Silverado and I'm so glad I did. These LEDs gave my truck a much more modern look and made my cargo lights much brighter and more functional. (Posted on 8/15/16)

Bright LEDs, great fitment Review by Clark

I got the HP36 for the cargo lights on my 2013 Chevy Silverado 1500. They were really easy to install and I had no issues with fitment. Definitely brighter than the stock incandescent bulbs. (Posted on 3/27/16)
Awesome cargo and reverse bulbs Review by Gmc dmax

Recently installed the xp50's in my 15 gmc 2500 super bright reverse and cargo lamps. Match factory led reverse lights on my tow mirrors. Super easy mod. (Posted on 12/15/15)
Look great with the stock bed LED's Review by Jakob
Quality Price Value
I originally bought the hp36 bulbs for my reverse lights, but happened to throw them in the cargo bulb slot to see how I liked them there. I liked the look so much, I left them there and ordered another set (xp50) for the reverse bulbs. I now have LEDs in my fogs, cargo, license plate, and soon reverse slots from diode dynamics. I also ordered HIDs for my low beams. The clean look of these bulbs really upgrade the look of the truck! I definitely reccomend their products and customer service. (Posted on 10/1/15)
