Troubleshooting Trailer Lights that All Stopped Working  

Updated 11/13/2025 | Published 10/15/2025

Question:

I own a 2017 rockwood mini lite model 1905 .On a recent trip all my tail lights and running lights on the back of my trailer quit working. I have no turning signal or brake light. Any suggestions as to what the problem could be? Thank you, Ed

Hey Ed, whenever all of the taillight circuits stop working at the same time the issue is the only they all have in common...which is the ground circuit. So you would want to check the ground ground of the trailer wiring and that is going to be the problem. It also can be just some corrosion on the pins of your trailer connector so try taking some sandpaper to them to clean them off. If it's not that it could be that the main ground wire has been damaged so check for that and fix as needed.

Hey Ed, did cleaning the trailer connector pins or checking the ground wire get your Rockwood Mini Lite’s lights working again? Your update could make it easier for the next person with the same issue.
