Are you referring to the trailer wiring kit you bought from us or the trailer lights I see that you ordered at same time?

I would assume it's the light kit part # TL29BK which since you tested and the lights have power ran to them that would indicate the issue is the ground circuit. These ground through the mounting hardware so make sure they are mounted to a clean metal surface. If you tested them before mounting them that would be why they aren't functioning since they wouldn't be grounded.
