Won’t last
I bought for my 2014 Silverado and I’d recommend buying morimoto. I’ve had these in for less than a year and I’ve got turn signals going out on both sides. Great design, wish they had a stock exterior lens instead of the bubble lens.

These things look great!
These things look great! Install was easy. Ensure you disconnect wiring harness clips to get the extra slack required. Once you do this install is super easy, took me less then 10 min. There is a video on YouTube that helps a lot. Only bad things I will say is you can buy these on Ebay for cheaper for the same product, but didnt find that out until after ordering. Also, the connectors that plug into factory wiring harness are tight. Make sure you connect the black wire side to the black wire side in factory harness the first time as you will only get one opportunity because the plug in on these is not conducive to plugging in and out.

Great tails except for one small detail
Fitment is great except for one thing. The male end coming from the tail lights to plug into the OEM socket is a tad too wide due to the clip on the inside of the tail light socket. Once I shaved that down some everything was a nice tight fit. Lights look/work perfect. We'll see how long they last. Fingers crossed.

TOTALLY SATISFIED! 🤩
I bought them in December 9th of 2020, today is July of 2023 and they stills looks and work perfectly like new!,just a very tiny issue in the socket fitment but I fixed it immediately, anyway I give them and totally deserve five stars 👍👍👍

Replaced resistors after 1 year in both lights, stopped working less than 2 years.
I love the look of these taillights. I had to replace the factory resistors after 1 year (no big deal). Resistors are to stop the hyper blink. Just shy of 2 years the right taillight stopped working. I want to purchase another set but I'm skeptical if they only last 2 years.

Definitely a 5 Star rating!
Overall the set of taillights are better than I expected. The fit perfect, instructions were clear, I did look up a video just to make sure I was doing it right. The backup light was added after. (LED) If you have a GMC and you want to give it that new look.

Very poor reliability
I’ve had to replace these twice. After contact customer support I was told the following. Thank you for reaching out. Please note that LED load resistors typically have a shorter lifespan compared to standard electronic components. It's common for them to last around 1 to 3 years, depending on how frequently they're used and the environment they're installed in. Since they generate a significant amount of heat during operation, especially in applications like turn signals or brake lights, it’s not unusual for them to wear out over time. If your resistor has lasted around 2 years, that would be considered within the normal range for this type of component. If you’d like to replace it, you can purchase a 12V 50W 3.4 Ohm resistor from most automotive or electronics stores. Just make sure it’s mounted securely to a metal surface for proper heat dissipation. Best Regards,Jasper Go Customer Service Rep So if you want to keep replacing them buy these or be told to fix them yourself.

Vraiment un produit de qualité et le branchement est facile à faire j’ai du contacter le vendeur pour savoir où était mon colis et ils ont tous fait les démarches pour moi très bon service après vente je vous le conseille fortement merci encore pour ce très bon service cinq étoiles voilà pour faire suite à la qualité du produit rien n a changé sauf la résistance fourni que j’ai dû remplacer à cause d’un problème clignotant trop rapide mais après le remplacement ça va très bien et c’est normal que ça devienne humide l intérieur est noir ça dégage de la chaleur entre les deux surfaces merci 👍

Fit and looks are great however the male plug does not match the female receptacle on original lights . Even though the check says compatible with this year of truck . No adapter csme with them to allow for the difference in plugs . No local company carried an adapter so guessing it would have to come with the lights . Also no provision to plug holes in the back of the lights to keep water out of the light . Overall i did make them work but could have been a much easier install had they had the proper plug or an adapter. 3 stars is all i can give for fit and looks , the extra work lost them 2 stars .

The site confirmed that these fit my 2017 SLT and the wiring is not compatible.

I bought these tail lights 1 year ago but didn’t install them right away. In April I installed them and thought they look great. Since then the right signal flashes twice like normal but then starts flashing very fast like when a bulb is out. That I felt was strange but they still worked. Now about a week ago the running lights have gone out and at night no one can see me from behind plus it’s illegal not to have them on. I can send a pic but it just shows the lights not on. Signals still work. Reverse lights still work but running lights don’t. They also say they are waterproof and yet I have moisture build up inside the lens. Please advise me of a fix or replacement of these lights. Thank you.
