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. 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: 

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. 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.

  1. Clean Bright Light Review by Tim

    Installation was a snap and now I have nice lighting for my reversing camera, way brighter than OEM bulbs.

    But, I do wish the HP36 had a bit more throw, maybe I should have gone with the XP50. (Posted on 6/30/17)

  2. HP36 210 lumen Review by Alberto

    Bought these as they were the brightest available at the time of purchase, 01/2016. Not as bright as expected. But noticeably brighter than stock bulbs. May purchase the XP50 in the future to go along with the brightness of the XP80 tail light bulbs. (Posted on 5/22/17)

  3. I can see in back of me Review by David

    I received the order placed on April 24th today, on time. I purchased backup LED lights (XP50) and LUXEON LED Fog lights for my Subaru Legacy 2015. I am extremely pleased with both the service that got the order here on time and the products.

    The backup LED lights installed and operated as described. They produce excellent illumination while backing in comparison to the stock incandescent bulbs. The backup camera image at night is greatly improved.

    Please accept a review of 'excellent' and my wishes that you continue the excellent service and delivering quality products. (Posted on 5/9/17)

  4. XP50 = money well spent Review by Michael

    I bought the XP50 bulbs. They are pricey. But it is money well spent. (Posted on 12/6/16)

  5. Excellent replacement choice Review by DanC

    Like another reviewer I chose the 'brighter than OEM but not super bright' LEDs. They are a definite improvement over the light provided by the bulbs Subaru chose, and well worth the money. (Posted on 11/16/15)

  6. Nice touch of class Review by Rod

    I received these yesterday, in the HP36 model, and installed it (too easy) and it gives a clear ice white shine when engaged. The size is amazing and the light output as well. I used it at night too, but didn't have much of an area to view how much they actually lit up the surroundings. Either way, great product as always. Maybe I'll get the 410 lumen version next time. (Posted on 6/9/15)

  7. Awesome Reverse LEDs Review by Spencer

    I bought the XP50 (410 Lumens) for my Infiniti, but sold the car and kept the LEDs. Installed them on my 2011 Subaru Legacy 3.6R and they fit great. These LED's are very bright, but expensive. (Posted on 5/21/15)

  8. Great Product Review by Steven

    Another quality product. My stage 2 lights didn't quite fit my 2014 Legacy but DD worked with me and helped me get some bulbs that fit. I wound up going with stage 3 and these things are bright! If you have tinted windows or just want a little more light for your backup camera, these are great. (Posted on 3/3/14)

  9. Great product, pricey for me though Review by Derek

    I love the lights, I just wish they were a little less expensive. Great output though! (Posted on 1/2/13)

  10. Great quality Review by Nathan

    I bought these for my '11 Legacy and they quality of the light is just amazing at night. I considered going with the super super bright ones but I'm glad I didn't. These give me a sexy European like look without out being obnoxiously bright. (Posted on 9/28/12)


Backup LEDs are a direct replacement. Just change the bulb! You will not need any resistors or other accessories.

Remove your factory bulb

  1. 1. Access the bulb or tail light. You may need to pull back the trunk/cargo carpet and/or unscrew the visible nuts holding the light in.
  2. 2. Remove the backup bulb socket by twisting counterclockwise.
  3. 3. Remove the factory bulb from the socket.


Install your new LED bulb

  1. 1. Plug new LED bulb into socket by pushing it in fully.
  2. 2. Test the function of the bulb. If it does not work, remove it, rotate, and reinstall in the socket.
  3. 3. Insert socket back into place, and reassemble as necessary. That's it!
