I researched and researched LED tail lights for my 2014 until I was blue in the face.
Didn't like the looks or reviews of any of them.

I ended up replacing stock halogen bulbs with LED bulbs in the OEM tail light fixtures (3rd brake/cargo light, plate light, front turn and parking light bulbs as well) and I've never been happier.
Had to install a resistor for the turn signals to prevent hyperflash but all went well..

Very happy with the end result..

 

Lesson learned OP. Stay with OEM parts always. Hope you get your issue resolved. if you end up needing OEM tail lights go to this place I got mine from https://www.toyotapartsprime.com/ . I like them since they have all O.E. parts but really cheap compared to the dealers.

 

Wow, I'm guessing I would have made the same mistake you did. I probably would have thought it was a standard warranty of a year or so, I would have never thought 30 days. I'm betting most guys run if they see that warranty...big emphasis on IF. Thanks for the heads up, sorry it happened this way.

 

I have the same problem with my tail lights, however only when I pressure wash directly on lamp. the moisture goes away after a while.

I also have headlamp from vipmotoz, poor light output and impossible to adjust correctly. Tried to contact and fix this with the seller on eBay, but communication suddenly stopped..

So lesson learned! quality cost.. should spend the money on quality parts in the first place.:facepalm:

 

A while back there was (still is) a grille that looks like Rigid, comes with lights too. I almost bought it, but then searched online and found reviews with issues, stating it was only a 30 day warranty from date of purchase. Gotta watch aftermarket stuff.

 

I had a similar "nope" with Morimoto LED fogs. Within a couple of weeks one began to show fog inside. They advertised a 10 warranty on their website. The owner claims that it's normal and will only replace it if the moisture accumulates to a "puddle". I'm kinda miffed, but I'm just going to have a go at trying to get it to seal up via DIY.

 

I think anytime you purchase non-OEM headlight or tail light assemblies, you already know they won't have the same quality control as OEM. So for the LED tails, I bought for my Toyota Pick Up ('91) I ran a bead of waterproof caulk around the seam to keep it from getting any sort of condensation. Just a thought for future.

 

The joy of Chinese EBay headlights or tail lights soon fades away
