FUNCTION

This 921 XP50 is a direct replacement for any 921 size incandescent backup bulb. 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.

NOTE: This is a highly-powered bulb, and is designed for intermittent use only (such as in a backup light). We have "juiced up" the power on this one to very high levels, which results in extremely high brightness. However, operation for more than a few minutes at a time will result in flickering. This bulb should not be used in continuous-operation applications.

 

BULB DESIGN

Each of the four sides of this bulb contains two 5W-rated CREE 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.

Included in your order is TWO BULBS.

 

COLOR

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

 

BRIGHTNESS

410 Lumens

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.

 

QUALITY

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.

    I love these bulbs. They are bright, and they seem more like 5500K-ish (not too blue-ish). I wish the price was cheaper, but I had to splurge & ordered 2 pairs for my GMC Canyon 2016. (Posted on 11/26/16)

    I ordered these for my 2016 UK version Mustang GT, dealing with DD is a breeze & my lamps arrived within a week, with full order tracking. Installation is so simple, direct swap out for the c**p stock bulbs. New lamps are bright & a huge improvement.

    This is a no brainer upgrade

    I must say that I was a little skeptical at first to dish out 90 bucks on backup lights that are theoretically only on for 10 secs at a time, however, the brightness is unbelievable. I initially had them on my G37 and now, my 2013 ML350. It gives you a true luxury OEM look. If you own a newer model German car, I recommend asking DD about a plug n' play resistor to avoid error readings - mine worked like a charm! Cheers! (Posted on 7/2/16)

    Bought these to replace a competitor's LED for backup lights on a 2014 F250. While the 410 lumen was a huge improvement on the "visual" illumination, the greatest improvement was the rear camera. Would recommend these to my friends....and have. (Posted on 6/21/16)

  10. Retract a negative view Review by Patrick
    Price
    Value
    Quality

    My first response was negative because upon installing the bulbs they didn't work. I turned them, as stated with LED bulbs and they still didn't work. (disappointed) Although, I called the support group, they advised me to reinstall the bulbs but, before I do, pull the wires out at about a 45deg angle and away from the bulb. So I did just that. I then installed the bulbs again and wah-luh, Light, extreme light as I was looking for. These bulbs make it very easy to see behind me in the dark and very good sight with my back-up camera. As these bulbs are very costly, I do recommend them, as they produce the light better than any other back-up LED. I have tried other back-up LED's, $10-$35 and they do not come close to the light that these LED bulbs do.

    Thank you

  11. And With This Light... Review by Mokoto
    Price

    Quality

    It was dark at night as I was running away from the foul creatures. They were jumping and clawing, crying and howling, rasping and thirsting. They wanted my blood and I wanted to see my family. I jumped in my trusty Subaru and realized that I had parked it facing a wall. Careless mistake and I was running out of time. I slammed it into reverse and heard shrieks of pain as the light was cast upon my pursuers. It was bright and glorious as I watched them burn on my reverse camera. When the ashes stopped falling and the blue warm engine light had gone off, I safely backed out of the parking spot with the vision that these lights gave me and went home.

    10/10 - would buy again. (Posted on 2/6/16)

    I purchased these for my 2016 Hyundai Tucson. These are extremely bright and much better than halogen bulbs. LED is a huge improvement, and the CREE LED chips are outstanding! Brighter than the typical 5050 SMD bulbs you see around. The build quality is superb and I am certain to buy more LEDs from Diode Dynamics. (Posted on 1/29/16)

    I installed my DD 921 reverse lights today replacing my ijdmtoy 921 reverse lights. Ijdmtoy isnt a bad bulb to have though it projected more of a blue hint over the cool white that DD projects. Granted my tail lights are tinted though DD bulbs just seem to always amaze me! Great products for sure! Thank Diode Dynamics! (Posted on 6/24/15)

    I first bought the 921 HP36 and since I tinted my tail light there were as bright as I wanted them. Because of there great customer service I was able to send back the bulbs and get the 921XP50. Yes there pricey but at the end of the day there were brighter and did the job. I install then on my 2015 Subaru Crosstrek Hybrid. (Posted on 4/11/15)

  18. 421 Lumen (Reverse Lights) Review by william
    Price
    Value
    Quality

    I had bought these as reverse lights for my Subaru Crosstrek. Using these 421 lumen (Each) with the back up camera, really helps when backing up at night. I uploaded a picture of my alley and to say that these are bright is a gross understatement. It's like having two surefire flashlights mounted to the back of your car. I debated giving price for these a four star, but in the end, I realized that we pay way more for foglight upgrades so $90 really is a bargain for how well they light things up at night. Another benefit for these is if your off roading at night and need to back out of a sticky situation, as I promise you won't need a spotter. Even if you don't have a backup camera, you will still benefit from these lights when looking over your shoulder when backing up. Every car I own from now on, this will be the first upgrade I make.
