Question:
All of the lights come on at the same time and stay on as soon as I plug it into the truck. What does that mean?

Hey Dan, thanks for the picture! Are the lights and their individual functions working on your trailer? Not sure what connector you have but the lights on the Hopkins 7-Way RV Style Trailer Connector w/ LED Test Lights item # HM48503 only come on when that functions being used.
I recommend checking your 7-way connectors and making sure they're clear of debris. Another thing you'll want to look at is your trailer's ground.
