Greetings all... Karen here. Just returned from a trip and were completing a wash of the rig. DH noticed a light turned on at the front wall of the trailer (driver's side). Can't figure out how to turn it off. All inside panel switches are off, tow vehicle is not running. We're clueless, first, how to turn it off, and second, the purpose of this single lamp. Any guidance would be appreciated. Thanks!
