Since you were so quick to pick, let me inform you that most all old truck campers and camp trailers really did have 120 volt interior lites in them, that operated only when plugged in. The first campers I had even had propane lites in them. So 128s post "newer" is correct

Actually if it is newer the lights are 12VDC only.
This has nothing to do with whether the trailer is older or "newer", whatever that might mean. Travel trailer interior lighting is 12 vdc and always has been, the exception being some large park model units which are 120 vac, aren't equipped with a battery, and don't have any 12 vdc capability ... but that's not what the OP has so it's therefore irrelevant to this discussion. :R
