Auxbeam Upgraded 921 Bulb for Backup Reverse Light, 44W 6000 Lumens 500% Extremely Bright 912 W16W T15 Bulbs, Error Free, Pack of 2

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.

Some of the best reverse lights I’ve ever had.

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

I have used AuxBeam for years and had great luck. I put these in my 2016 Ford SuperDuty as back up lights…. Insane is under statement 100/10

These are easily the brightest backup lights I've had in a car. Living in a more rural area, seeing behind you at night is more important than you'd expect. These lights did the trick. For installation, you just have to make sure there is sufficient room behind the light socket for the cooling fins. The tabs to hold the lights in are a rubber, universal fit. I would recommend mounting them so the LEDs are facing horizontal for the best light pattern. They claim the pattern is even all the way around, but it is not. Also, the wording is "up to 6,000 lumens". I can say these are no where near that. Maybe if the car is running at 16V rather than 12 to14V, but I still doubt it. Even so, I'm buying another set for my wife's car.

These things are stupidly bright and is always my go to backup bulb. Best brand in general I’ve ever worked with so 5 stars

Worked perfectly in a 2011 f250 super bright and satisfied

Much brighter than expected, i like things overly bright and this does the job.
