AUXITO Latest CANBUS 3157 Switchback LED Bulbs 3057 3457 4157 Dual Color Amber/White Anti Hyper Flash Built-in Resistor Error Free Turn Signal Lights and DRL/Parking Lights, Pack of 2

Great idea. Poor execution. It is June 21st 2025. I purchased these in April 2025 to replace other LED bulbs that required a resistor. I removed the old resistors and bulbs and installed these with built in resistor. Install was easy. 20 minutes on a 13 buick regal GS. SUPER BRIGHT. They worked great with no hyper flash for about 3 days. Then they decided to hyper flash intermittently. No rhyme or reason. Sometimes switching back and forth between hyper and regular flash during the course of a few minutes while sitting at a red light. Although they still worked, the hyper flash / regular flash back and forth was at the very least, irritating, annoying and distracting and definitely a cop magnet. Because you wonder....ARE THEY EVEN WORKING AND WHY ARE THEY FLASHING SLOW THEN FAST THEN SLOW? 60 days in now. LED Failure in one bulb already. Only half the LEDS light up anymore so one tail lamp is half as bright as the other. Again, frustrating, annoying and a cop magnet. I purchased another set today @ another $40usd. If these last for a year(which i think for the money one year seems reasonable)? I'll edit my review. If they don't last I'll know it's a bad product overall and go back to the resistor set up.

Lights are BRIGHT, much lighter than stock which is immensely helpful on rural roads with minimal surrounding lighting. Now this is very much a “get what you paid for” situation, paid about $13 including tax for this set including using a coupon. Quality is GREAT, can’t say that enough. However I bought this exact same set in 2022 almost exactly a year later they went out, bought a second set so 2023, and now 2 years later I’m on my third. I love them so as long as I get another 1-2 years out of these I will buy them again, especially for the price. If you expect longer than that might want to look elsewhere. Only reason for losing a star was how long they last. Update April 27: I purchased my 3rd set of these back in February and as noted above was fine with getting 1-2 of life out of them for the price, however this third set lasted less than 2 months. Can’t say they were bad out of the box because they worked great, but quality has gone downhill. Dropping from 4 to 1 star, and of course right outside of return window.

I have gone through two sets of these lights since March 2026. They are very bright and works great when new. Once it gets older, it will hyper flash or not work. First set started hyper flashing within a two months, second set also lasted two months and now it hyper flashes. I do not recommend these lights at all.

I purchased my first set less than a year ago love how bright they are but longevity is not there. So I bought a second set being optimistic that I'll have better luck. But this time they lasted 30 days. I will not purchase again. They did not stop hyperflash the second time around

Company does not stand behind their bulbs. I spend over $50 to have these bulbs installed in my C6 Corvette. On the Corvette a wheel needs to be removed for installation on each side. One of the bulbs is defective in that it flashes fast when it gets hot. The other bulb is great. I asked to company to send me one new replacement bulb so I I won't need to have both removed for a return to save on installation cost. Their answer was to cancel any returns and tell me it was the car's fault the bulb didn't work correctly. I'll give them one more chance to replace their bad bulb. After all products do fail once in a while. If they don't make this right, I'll be on all of the Corvette owner sites to warn about this manufacturer so this doesn't happen to someone else. Purchase at your own risk. There are many of great alternative products available on Amazon.....

I bought the version with white/amber for my daytime running lights. However, they are amber regardless of daytime running lights or turn signal function. I'm not sure what the purpose of the dual color is. They are extremely bright. They do work without the rapid flash like the other version I bought. They are very hot. I thought LED's would be nice and cool. Too hot to touch after being on for just a few minutes. Update 9/26. I bought these back in June. They have been working up until yesterday. I turned on my blinker and it fast blinked, then it slowed down and went back to normal. Other times, no fast blink. At the price I paid for these I am not impressed and from what I have read the 2 year warranty only applies if you bought direct from Auxito. Stay away. Update: Auxito sent me a replacement bulb but they wanted proof that I destroyed the old one. Sure, let me risk cutting myself or getting glass in my eye so you can have your proof I destroyed it. I didn't bother. They still shipped the replacement. It worked for about 6 months and the other day it started doing the fast blink crap at random again. I am not risking getting in an accident or getting a ticket because these things suck. I put my old regular bulbs back in.

Bought these around may 2025. Good at first. Then Started making loud fan noises. One of the lights finally gave out today. Replaced both with stock bulb. Tried lasfit before this. Same issue.

They have worked perfectly since I ordered them in February. All of a sudden, a week or so ago, they started throwing a code in my truck. The driver's side brake light bulb has now stopped working. I pulled the housing to look at it and removed the bulb. While removing the bulb, one of its leads came out of the housing. I have attempted to contact Auxito twice now with absolutely no response. I have replaced the bulb with the old incandescent, so I will have running and brake lights for the time being. Has Auxito stopped supporting customers?

Love it , very bright! Looks good. Installed it yesterday, still need to try it on for the rest of the time.

Fits perfectly and the visibility is also good compared to a stock (halogen) bulb

Aluzan muy bien y de fácil instalación

Works great in my 1997 f150. Nice and bright, no hyper flash issues at all. Only built in resistor turn signals that have worked with no hyper flash for me.

Finally! An LED that works, without extra resistors and without causing and error code and hyper flash! I've gone through a few different bulbs and failed with them all. These Auxito bulbs hit the mark! Worked immediately, no codes! No hyper flash! One minor criticism... The bulb base is not a great fit in my W21W light socket. I really had to manipulate and push very hard to get them in. I'm actually probably going to take them back out to see what adjustments I can make to help them go in better. I feel like they may be at a point that they may pop out with a solid bump. My ride is a 2020 Chevy Suburban (Premier). So they should work for 2015 to 2020 Suburbans! They turn on and off crisp, unlike the factory halogen. Red bulbs in red rail light lenses do work the best! I had my suspicions but the internet was right again! The picture does no justice. The left ones are the Auxito. The LED (Auxito as well) reverse light bulb steals some of the show. Ignore the grocery bins and installation tools :).
