Ok first I will describe many (but not all) rv Light systems
There are ceiling lights. Down lights. "Local" lights and asile lights.
OFten the main lights have a switch on the light. may be on/off or 3 position.
"Local" lights (like over the dining table) will usually have on/off switches.
You have a main control panel somewhere (This has switches and indiators on it) that may have a LIGHTS switch
Just inside the door is a panel of switches. Usually you find the main Use/Store or battery switch here. there will also be a light switch. (or 2)
and there may be a switch on the dash. Sometimes there are two or three switches in a multi-switch system
And in some RV's it's an electronic module that controls the lights via relays and on/off push buttons or rockers (These will either be ON/OFF buttons or 3 position rocker switches spring return to center)
All depends on the RV.
