Help!! installed LED tail lights now truck won't start

Hi All,

This is my first post as a new member and need some advice. I have a 2018 tacoma off road and installed new LED blacked out tail lights. The right side tail lights and turn signal did not work. I then reinstalled the original tail lights and everything worked fine. Thinking I may have not hooked up the LED's correctly I installed them again. This time my truck would not start and doesn't turn over.

I replaced the lights again with the factory lights and disconnected the battery hoping to reset something but had the same result.

I have seen online the the LED's may cause some problems with the regulators. I am hoping I have not damaged the computer or something.

Any Advice?

I have attached a picture of the truck as Im pretty stoked on it as I know everyone on here is about tacoma's. Having it not start is a real ball kicker!!

 

I've heard some aftermarket taillights have been shipped wired wrong or backwards. Don't remember the brand name but I would check fuses

 

Check your fuses under hood and under driver side dash.

 

Garbage aftermarket parts strike again...

Another vote for fuses.

 

Sorry forgot to mention I already checked fuses.

 

Including fuses in the engine bay?

 

You didn’t check them all, because when you found the blown fuse, the car would start.

 

Just gotta get stuff from tacoma beast, its more expensive but good quality and just works

 

Rodger that... Ill double check again.

 

Yeah I got the Prinsu Rack from them and an ARB compressor. I wish I got the tail lights from there too.

 

Hope you figure it out. Good luck, I know it is frustrating.

 

Could always return them and then order from tacoma beast, i did and i love mine.

 

Check battery terminals. Maybe loose? Or have some corrosion? Good luck OP

 

Wasn't there just a thread about this a week or so ago or am I having some weird deja vu moment?

 

A fuse doesn’t have to appear blown to be blown. You need to check each one for power and make sure it is working that way.

 

Hey I bought my tail lights from Tacoma Beast, and my 2016 Tacoma did the same thing. Is Winjet LED Tail Lights just not work with the electrical system in these trucks or is it just defective lights they sent me?

 

What fixed it for me was switching the 10 stop fuse under hood to 30 and the 7.5 tail under dash to 15. Haven’t had problem since

 

3rd gen trucks: blow a tail light fuse lose staetability of the truck.

That's the legendary quality I have come to expect out of Toyota after so many years.
