AUXITO LED Brake Tail Light Bulbs 3156 3157 LED Bulb Red 400% Brighter 3056 3057 3047 4057 Led Bulbs for Tail Stop Brake Signal Parking Lights, Brilliant Red

These AUXITO 912/921 LED backup bulbs are a game-changer! The difference between these and the stock halogen bulbs is truly night and day. They claim 400% brighter, and I believe it – the 42-SMD chips put out an incredible amount of clean, 6000K white light. Reversing at night is so much safer now, as my backup camera view is significantly clearer and brighter, illuminating everything behind me perfectly.Installation was incredibly easy. They are non-polarity, so I didn't have to worry about which way they went in, and they fit perfectly as a direct replacement for the old T15/921 bulbs. No flickering, no errors, just instant, brilliant light.If you're looking to seriously upgrade your reverse lights for better visibility and safety, these AUXITO bulbs are an excellent choice. Fantastic brightness, easy installation, and a crisp modern look. Highly recommended!

Got these to replace my rear turn signal lights, which were traditional bulbs. All the yellow coating had flaked off over the years. This fit perfectly, and emits a deep, full amber light. I bought this brand because I'd gotten the same brand (Auxito) recently for headlight bulbs and theirs fit when others would not. I'm very pleased to have gone with this brand again. Good price, fast shipping and they look great.Update: they started "hyperflashing"--causing all 4 turn signals to flash really fast. This is possible with any LED bulb-they don't draw as much current as a normal bulb, so your car thinks you have a bulb out and tries to tell you by flashing quickly. So I'll need to get an LED-compatible flasher relay for the car. but they are still great lights!

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.

Nicely made bulbs. An exact fit, and much brighter than the original incandescent bulbs on my 2014 Toyota Sienna. In this vehicle the bulb serves 3 functions: marker lights when the headlamps are on; parking lights; and turn signals. All worked, excepted the turn signals had a high flash rate with the factory relay. The relay needed to be replaced with a LED compatible unit to fix this. This essentially doubled the cost, and the amount of work to replace the bulbs.

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.

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

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

Bright and work well but fail in a few months.
