Scare light query

Do you have a remote? My understanding is that if you turn it on with the remote, you have to turn it off with the remote.

Sounds like a bad switch. Pull it out and you should see three wires. Hot in, ground and hot out. You can at least kill it there until you get a new switch.

I suspect you are going to have a real fun time on your first trip to a campground. That will be a pretty bright light burning all night long...

My scare lights which are on both sides of my fifth wheel on the rear sides has a control switch near the full size picture window on the rear wall of the trailer. It is not near the entrance door access. Mine is also not labeled - Just a switch on the wall...

This always 'ON' light will also run down your battery real quick as well if you are running without shore power connected. I would look all around the living area for an unmarked switch.

I actually find it hard to believe it is always on. It would not last sitting over night when on when parked anywhere. This light should run from 12VDC which gets it power from the trailer battery. When plugged into shore power the on-board converter/charger keeps the battery charged up... I'm suspecting your battery is either dead or not hooked up and the scare light only comes on when you are plugged into shore power ???

There isn't another switch is there?

look at switches, if all switches are in off position, it's probably as RAS43 said.

Could be a bad switch. Open up the panel and disconnect a wire from the switch and see if the light goes out.

Just asking, are you sure the switch you are operating is the one that controls the scare light? Scare light switches are normally near the door.
The switch you are talking about might operate something else like the elect. side of the water heater, or tank heaters, or, etc.
