Ford Powerstroke Reverse/Backup LED Bulbs! Plug & Play Install! Increased Visibility!



Ford F-250 / F-350 Powerstroke Reverse Light LED


At Diode Dynamics, we carry a full line of LED bulbs, including three different levels of brightness for your reverse light or backup light bulb (921 / 3156 size). We carry the brightest, highest-quality bulbs on the market, which we have designed in St. Louis, Missouri. Your order will ship same day, and we're here if you need us for support and service. Every bulb carries with it a three-year limited warranty.

Your purchase includes two LED bulbs for perfect fitment in your model year selection.


Bulb Design


HP11: Four side-firing 1.5W-rated Osram LED chips, and one 5W-rated LED chip on top, which is projected by a lens for maximum effective brightness. The bulb is housed in a machined aluminum casing, which provides superior heat diffusion for long life.

XP80: Each of the four sides of this bulb contains three 5W-rated chips, and the top is fitted with four more under a projector lens. This is the brightest self-contained automotive LED bulb on the market, and is housed in an aluminum casing with a textured finish for maximum heatsinking properties.

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.

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. 1997-2010 F-150 Model Years / 1999-2006 F-250 & F-350 Model Years(3156) use a quality inject-molded 3156 terminal, with a locking base connector and proper pin alignment, designed for exact replacement of your factory 3156 bulb.

2011-2014 F-150 Model Years / 2007-2013 F-250 & F-350 Model Years (921) 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.


COLOR

These LEDs illuminate in a crisp, cool, bright, white hue for maximum light output.

BRIGHTNESS

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:

HP11: Slightly higher brightness than OEM bulbs.
XP80: Much brighter than OEM bulbs. These are bright!

HP5: Slightly lower brightness than OEM bulbs, but still provides the crisp, modern instant on/off of LED technology.
HP36: Slightly higher brightness than OEM bulbs.
XP50: Much brighter than 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.


QUALITY

LED Components. Diode Dynamics uses only the highest quality LED chips in the production of its bulbs. This means 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.

Hey Nick, you think these will survive under our hoods?
Heat is the biggest enemy of LEDs

However, we've installed LED "engine bay" lights in numerous vehicles, and haven't encountered any issues, even with FI applications. (I don't foresee any issues)

If you are looking for a light for more visibility when your hood is open, the HP5 will provide plenty of output.

92 lumens is enough to brighten up your entire cab FWIW

Plus, our products come with a 3-year limited warranty

Here's an installation video of the typical process:

Do your LED's function well in extreme cold? What temps have they been tested in?
I'm interested mainly in the reverse lights, but maybe the under hood light too.

Our LEDs work well in all types of weather. They are exceptionally well-designed and won't fail in harsh cold or heat.

(We have dealers in Alaska who've installed them and had great results)

If you have any questions about the design, feel free to give us a call: (314) 205-3033

They are backed by a 3-year limited warranty as well :thumb:
