AUXITO 912 921 LED Bulbs for Backup Reverse Light Bulbs, 42-SMD 400% Brighter, 6000K White, Non-polarity 906 W16W T15 921 LED Bulb Direct Back Up Parking Light Replacement Lamp, Pack of 2

I deliver newspapers for a living, and as part of the job I am often backing into/out of driveways and executing tight turn-around maneuvers in the dark. Being able to see is "kinda" important. While the factory incandescent bulbs of my '99 Jeep Cherokee were good, I was searching for something better. Being that my vehicle is wired using the "CK Method," I needed to make sure any LED replacements were compatible with this wiring system. (LED bulbs that are incompatible will blow fuses immediately, so it's definitely something buyers need to be aware of.)These Auxito LED bulbs ARE compatible with both "Standard" and "CK" wiring, and are designed to eliminate the need to check proper polarity - in other words, these bulbs will work no matter which way you install them into your sockets, on the first try. It takes more circuit design know-how and electronic components to achieve this, so I appreciate the extra thought and production costs invested - Auxito could have taken the cheapest route to maximize profits, but they didn't.According to what I've been able to glean from the item description, these bulbs are not compatible with vehicles that use CANBUS. I don't have any vehicles that use CANBUS communications, so I cannot verify - however, there is a CANBUS-compatible version from Auxito; if you have a vehicle that uses CANBUS, I would highly suggest you choose that bulb instead. (Unsure if your vehicle uses CANBUS to determine if a bulb is out? You might want to consult a repair shop, preferably a dealer that sells your car's make because their Service department should know that.)I've had them installed in my Jeep for several months now, and the difference is almost mind-blowing! Bright, crisp "pure" white (not that bluish-tinted "cooler" color temperature) that illuminates everything behind me very well. I don't see any odd "hot" or "cold" spots in the light output, as is common with some other brands. I have seen no drop in total light output over time (LEDs get dimmer if they're being "pushed" too close to the "limit"), and believe me when I say my backup lights easily see 10x the use an average driver will subject them to.I have not installed these bulbs in a place where they see constant operation (parking lamp/turn signal or tail/brake) but I feel pretty confident in saying they'd be a great upgrade for those applications as well.I'm quite impressed with these bulbs, and I would highly recommend them to anyone looking for brighter illumination when reversing - or, if you're converting your car to all-LED for the aesthetic and want an amazing bulb for your reverse lights.In fact, I'm so impressed with these bulbs, I'm about to add another two-pack to my cart to replace incandescent reverse lights in my mother's '07 Grand Caravan, a vehicle that SERIOUSLY needs brighter reverse lights due to the factory window tint.

This was a great upgrade to my backup lights on my 2018 4Runner. I have a pretty dark driveway and was having issues seeing the driveway in my backup camera. After backing up in my lawn a few times I decided I needed to do something about seeing where I drove. I originally researched adding external lights, but then I saw a comment where someone upgraded their existing bulbs which was a much easier solution. I researched different LED bulbs and decided these were the ones I wanted. After installing them I can easily see my driveway in my backup camera even on the darkest nights. So glad I picked these up, you won’t be disappointed if you do the same!!

Very bright light. Fits like OEM. For several days there was an odd error that showed up on my dash. This is a known issue but the Ford F150's computer reset itself after a few days. Having installed the lights many months ago, error hasn't shown up again.

The item is great but why does my turn signals blink super fast now.

Nice headlights for Garden Tractors. Time will tell if they last in the role, but I like them. And I'm picky when it comes to the old 2004 John Deere GX335. 614 hours and she purrs like a kitten.

Bright led lights to replace my 2003 Chevrolet Monte Carlo reverse backup lights! Great quality, very bright, work great!

So much more better than the original dull soft yellow amber lights. Even during the day as u can see it just makes the car look better and so much more brighter to blend in with all the other LED lights. Quality is great. Perfect size and fitment. Overall I recommend anyone who has p21w or 1156 bulb sizes.

These bulbs are bright day and night and fit perfect like OEM !
