Need help! Switched trailer lights to led now they won't work.

Like the title says. Converted my boat lights to led and now they won't work on my truck. Its a 2017 sport with tow package. It worked before with the old bulb style. It also works on my other vehicle and a friend's truck. I've searched everywhere and can't find any solutions to this problem. I want to go boating HELP!!!!

LED's are polarity sensitive.

 

Most likely you have at least one led wired backwards. Power will only flow one direction with LEDs if one gate is backwards it creates a dam and stops the flow of current, test your polarity before installing.

 

Yes I have tried switching the polarity. It did not work.

 

I’m pretty sure there is a fuse for the trailer lights in the truck. Have you checked that?

 

Replaced the harness and lights. Works now.
