Subaru Legacy GT Reverse/Backup LED Bulbs! Plug & Play Install! New Bulb Models!

At Diode Dynamics, we carry a full line of LED bulbs, including three different levels of brightness for your LGT's reverse light or backup light bulb in every major bulb 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 Subaru Legacy Model Year Selection.

Bulb Design

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.

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.


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:

(921 Bulb Models)
HP5: (92 lumens) Slightly lower brightness than OEM bulbs, but still provides the crisp, modern instant on/off of LED technology.
HP36: (210 lumens) Slightly higher brightness than OEM bulbs.
XP50: (410 lumens) Much brighter than OEM bulbs. These are bright!

(1156 & 3156 Bulb Models)
HP11: (310 lumens) Slightly higher brightness than OEM bulbs.
XP80: (510 lumens) 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 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 i just bought a 2012 gt and i need to change all these dull lights lol. what would be suggested for brightness.

Diode Dynamics 03-23-2012 02:18 PM

I'd highly recommend our 6W model! Got them in my car and I love them. -Paul

Feel free to bump all of your threads at one!

Diode Dynamics 04-02-2012 04:11 PM

Well thanks for the free bump!

Drew888 06-12-2012 12:18 PM

Paul, have you experimented with any other lights? Reason I ask is because I just saw a friends reverse LED bulbs that were crazy bright but did nothing to light up the ground.

Yes people will know your coming but I'd prefer throw over brightness.

Just curious, thanks.

Diode Dynamics 06-13-2012 03:19 PM

These are for the reverse LEDs, the high power are very bright.

ColdBore 08-03-2012 05:10 PM

Will be purchasing very soon since i painted my tails =] looking forward to the 6W

Have you fit these on an LGT wagon?

Diode Dynamics 08-31-2012 05:58 PM

No, not here in the shop. However, we have designed these so that they are the correct diameter to fit any proper size (921)
