***Updated review. Seller states there is a one year warranty. Seller contacted me and has indicated they will not send a replacement or honor the warranty until I change my review. TUINCYN should not be allowed to sell merchandise on Amazon or anywhere else. I still have the bad part and they refuse to honor the warranty because I won't change my review. Honestly, who changes a review unless there's reason to, such as good customer service and a replaced part. To hold a warranty hostage to a good review prior to any change in status is criminal.After a couple of weeks, one of the lights led at the tip of the unit started flickering. this is the led behind the halo end, so it's extremely obvious. Bottom line....they won't last more than a few weeks let alone however many thousands of hours they claim to be good for.

I got these June 2018. at first they were fine. they did the work. I have a Chevy cruze 2014. then 2 lights started to flicker around October. I think to myself I'll let the seller know since I couldn't return it to amazon.I speak with seller, but he is not communicating well and asking for unnecessary info, or info he already has. I know this because I sell on Amazon myself. anyways, he says hang tight, replacement is on the way. it takes over a month to get here because they were shipped from China. 🙄i had to reinstall the oem lights I had while I was waiting for this trash to arrive. once I got them, I installed and my car was back with led lights. now some other lights started to flicker and die. one more dies. like 2 weeks later, another one dies.at this point, I don't wanna deal with seller, so I reinstall the halogen bulbs from before. very recently, one more bulb died on me and now I've had enough. I ordered some better quality bulbs, even though they were just a bit more expensive. once I began replacing all bulbs, I could see that the last existing bulb would eventually give out.5/ 6 bulbs died. only one remained. you tell me if that is okay. SAVE YOUR MONEY AND STAY AWAY FROM THIS PRODUCT.

Review is for the amber version: Whilst nice and bright, this is a two "filament" design, the higher powered circuit is barely brighter than the low power circuit, this makes them useless for combination turn signal/driving light setups. I'll be returning these.

I put these in a 2013 Dodge Challenger and the middle part of the tail light was fine but the outer turn and brake lights don't like these bulbs. I put one load resistor and it has the hyper flash problem and I put two and then when the tail lights are on they don't get brighter with turn signal or brake lights.

Plugged into 97 Chevy 1500 and turned lights on just to blow a fuse and melt the 3157 light socket. May work in other but I do not recommend!Update 1-18-18Seller has agreed to replace the defective bulbs with new ones.

I bought two sets, the first set lasted 2 weeks, led's started dying out. the second set lasted about 2 months, i mixed and matched as the bulbs died out, what's left (about 20%) now blinks. Not worth the return shipping.

Every single bulb had LEDs burn out within weeks. I mean EVERY SINGLE bulb. You'll probably find out when you get pulled over and the Cop tells you your break lights are flickering randomly. DO NOT BUY.

Not as bright as I expected. The glass bulbs I had are little dim from these.

THESE ARE NO GOOD TO PUT INSIDE OF YOUR TAILLIGHT OR HEADLIGHT LENS THEY OVER HEAT AND STOP WORKING.BECAUSE THESE BULBS ARE POLARITY LED BULBS YOU HAVE TO HAVE NON POLARITY BULBSTHIS IS HOW A POLARITY BULB WORKS YOU CAN ONLY GO -- + WITH THESE BULBS IF YOU PUT THIS BULB IN BACK WORDS YOU WILL BLOW A FUSE.AND IF YOU USE A NON POLARITY YOU CAN TURN THE BULB EITHER WAY LIKE -+ OR +-

Product was as advertised and delivered on time. Much brighter then original factory bulbs. Installed these on my 2005 Toyota Tundra and am very pleased with the improved visibility. To prevent hyper flash you need to install a LED signal light flasher relay when switching to LED bulbs.

Seems like good quality however after couple weeks use, they're failing. Some leds don't work anymore and they flicker. I have them on my front signal lights with clear lens, they do not flash properly when using with lights on. DO NOT BUY!

They work amazing as a tail lamp or brake lamp. However for my truck (2011 ram Dakota) where the brake/tail lamp is also the turn signal, when I have my lights “on”, the turn signal does not light up. If you only need a brake or tail light, or are using this for a dedicated turn lamp only, you’ll be just fine

Installed these brake/signal lights in my 2012 Dodge Ram. Worked for about 30 seconds and then triggered an error code on the dash and began flashing fast as if a bulb were out. When ordering these I filled out the make/model entry to ensure proper fitment so I’m pretty disappointed with them.
