Running Lights Wont Turn Off

Hello. We have a 2018 DX3 37TS. Recently, we've had an issue where when parked and connected to shore power our exterior running lights turn on randomly and wonít turn off. I can't find a single switch on the dash that isn't already in the off position.

I find it largely depends on the rain, so assuming it's condensation or something on a connection in the engine bay. Only way to solve it so far is to remove the fuse in engine bay or turn off the engine battery disconnect. Iíll take it to Frieghtliner, but wondered if anyone else had the issue first.

Depending on how much rain we have, the lights can go dimmer or brighter. Sometimes the brake lights even appear to have turned on. Has anyone ever had this issue?

Not had that issue, but I would look at the trailer wiring harness. It could effect the parking and tail lamps if water is infiltrating the connector or where they spliced it in.
