Best bulb to replace the yellowish factory reverse light.
I installed these in my 2024 Chevy Silverado 1500 ZR2 and they are brighter than my factory LED headlights. I love these and they are very easy to install.

Very bright and well worth the purchase
I bought these reverse lights for my 13 F150. I have tinted windows and it's hard to see when backing up into my driveway. These reverse lights are really bright and well worth the purchase. I no longer have to roll my windows down to back up. I will definitely buy Auxbeam for my other vehicle. I tried looking at diesel leds for my truck, but I wasn't spending $104.99. Auxbeam is much cheaper, built really well, and definitely worth the money!

Bright and Reliable – Perfect Replacement Bulbs
I installed the Auxbeam Upgraded 921 bulbs, and they’ve been great. Super bright, clear light, and they fit perfectly without any warnings or flickering. Been using them daily with zero issues so far. Solid upgrade if you want dependable, high-quality replacement bulbs that perform exactly as advertised.

Fits Mazda CX9 *mostly*
MAZDA CX9 2016-2023 These bulbs do fit in the reverse lights and man are they bright! Its like headlights for the rear. That being said, the cover panels will not close *completely*. They will have one corner slightly popped out from the large bulb, but its hardly noticeable, and worth it imo. Im so glad these fit and look forward to many well lit nights

Great product
This is a great quality LED, super bright and well constructed. The fitment listed is incorrect for 2019-2024 Chevrolet Tahoe. It states it will fit but there is not enough room between taillight housing and main body of Tahoe. 921 bulb will fit as long as it can use the existing light socket, this particular LED has its own housing which sticks out about an inch outside of the main tail light housing. I have used this same product on the newer Chevrolet pick ups and it fits perfect.!

Good at first, but quality and support fell short
These Auxtio reverse lights were great for the first week—bright, clean output, and a nice upgrade over stock. Unfortunately, one of the bulbs started flickering shortly after. I reached out to customer support and went through their whole self‑diagnostic process, provided my vehicle info, and answered everything they asked for. After that, they stopped responding completely. It’s disappointing because the lights could be solid, but between the early flicker and the lack of follow‑through from support, I can’t confidently recommend them. Hoping others have better luck, but my experience wasn’t great.
