Product Details

ACME: Picked up the call from consumers who want a product that meets their expectations but aren't ready to break the bank. Their entry-level gear is the new industry standard that delivers real performance at the right price.

ACME: May be the "value" brand up and comer, but the Backfire 921 LED reverse lights are crazy bright and their bang for the buck is undeniable, that's for sure!

Features: There are 10 CREE LED's mounted to each backfire bulb that are kept cool by an integrated machined aluminum heat-sink – which is a good thing because these suckers are driven by a whopping 50W of power – more than any other reverse light bulb on the market by far.

Numbers: 500 lumens of theoretical output, measured output of 340 real lumens projected in a full 360 degrees to make sure the full surface of your reverse light reflectors is taken advantage of. No point in making a ton of light if it's not being picked up by the reflectors that are responsible for distributing it on the ground!

Lifetime: With all this power in a tiny bulb, you'd think lifespan would be a concern, but really – unless you spend hours on end driving in reverse, there's not much to worry about here. We stock, sell, and service a huge variety of LED bulbs and rarely (if ever) see problems with 921/T15 LED reverse bulbs due to the fact that they simply don't get used in any gear but reverse. Makes sense.

Trusted: For more than a decade, we've worked hard to earn our killer reputation. Car guys world-wide know that TRS carries the internet's best selection of high performance automotive and powersport lighting products at the best prices, and we've got the best, most knowledgeable team of real enthusiasts to help back it up. If we sell it, then you bet we've put it to the test on our own cars, trucks, and bikes. Need a recommendation on parts for your project? Got a tech question? Wholesale inquiry? Contact Us

Back up lights

Jack Downey Reviewed: 09.14.2017

Replaced the reverse lights on my 14 Superduty with these and they just barely fit in the housing! Crazy bright compared to the factory bulbs to the point you can't hardly look at them directly. Also gave the truck a much cleaner look without the dull yellow incandescent.

Great back up bulbs

Eric Yom Reviewed: 10.27.2016

These are great T15 bulbs for reverse lights. They are moreso 5500k white than the 6500k hyper white but they illuminated better If your vehicle reverse lights are t15s then these are your best bet. I wish I could post pictures to show the difference.
