trailer wiring- no tailights

[kuips]

was hoping to get some guidance on what my problem is........

I trailered my sled home today and noticed I don't have running lights. Brake, turn, four ways, license plate light, and side ambers ALL work! Tomorrow I will check voltage at the plug on my truck.... I believe just put the leads on white and brown to confirm there is 12v? thanks ahead of time for your suggestions.....

oh, its just a normal wiring harness, just a white, brown, yellow and green.

bulbs or LED? If bulbs, check them.

checked the connector on my truck, had 12.01V.
next i removed the tailights, and there was my problem. clearly the connection where the rear lights splice into the brown wire had come loose. was an easy fix and now can move on to bigger projects!
