The rear lights that turn on when you turn on your headlights do not turn on. My turn signal and brakes work just fine, but the low power lights that come on with the headlights do not turn on.

Hello, I am Danny.

Let me ask first have you checked the taillight fuse? I have attached a picture. The fuse is in location #9. I have attach a link on how to check a fuse.

Tried swapping fuses, and nothing. The lights on trailers work, I have a plug and go connector.

Hello again.

Okay, let me do some research and get back to you. Also, do you mean you have a trailer hooked up and the taillights on the trailer work but not the truck at the same time?
