AUXITO LED Turn Signal Bulb 3157 LED Bulbs Amber Yellow 400% Brighter 3156 3457A 4057 4157 LED Bulb for Front Rear Turn Signal Light Blinker DRL Marker Parking Lights, Pack of 2ClimatePartner certified

Great buy. Nice and bright. I bought two sets of these as I intended to use them as turn signals and day time running lights. However my 2003 Silverado did not recognize them as having blinker functionality. They blink / pulse, but the truck didn’t like them and acted as if I had a bad bulb (Rapid blink). Going to go ahead and leave 5 stars, however, description should be adjusted. This bulb, at least this color, did not work as a blinker bulb.They work great for day time running lights though and I’ll likely (hopefully) use the second set as reverse lights once my truck is out of the paint booth.

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.

Miles better than the regular bulbs. I installed them as reverse lights in my 2024 Corolla Cross. They improved the reverse camera visibility as well. Direct replacement and did have any issue with the polarity or anything. May be I installed them right the first time around. But regardless, so far they are working flawlessly. Just a little longer than the regular bulbs, but that is not an issue. There is enough room in the enclosure to fit these lights.

lights work good not great. They have a very fast blinking speed and the dash display said the bulbs both right and left are burnt out but both work. They are pretty bright though.

I installed these LEDs in my 2009 Mercedes CLK 350, and they worked flawlessly right out of the box as reverse lights. If you’ve ever upgraded bulbs on a Mercedes, you know how picky the CANBUS system can be, but these bulbs didn’t trip any errors or warning lights at all.The brightness is a huge improvement over stock, with a clean white light that gives the car a more modern look. Installation was quick and easy, and the build quality of the bulbs feels solid and durable. They've been running for a few weeks now with no flickering, dimming, or heat issues.If you own a CLK or any Mercedes from this era and are worried about compatibility or dashboard errors, don’t be, these bulbs are truly CANBUS-compatible and work perfectly. Highly recommend!

Got these Reverse LED bulbs for my girlfriend's 2013 Toyota Corolla. Recently installed a backup camera for her, and these LED bulbs illuminate way more than the regular bulbs. You can see the backup cam a lot better at night, and you can see whatever's behind you in the side mirrors and rearview mirror a lot better too. The lens on the front of bulb helps the light project outwards. They fit perfectly and match well with the other LED bulbs I've installed throughout her car. Can't go wrong with these.

Great upgrade for a reverse bulb! Quality is top notch works amazing, super bright .

Good replacement for halogen bulbs on tractor. Much brighter, but not nearly as bright as an LED lightbar if lots of illumination is needed for working.
