Main light panel and control panel for water pump, outside lights and inside lights is right inside the main entry door, behind a cabinet door. Only problem is, its so high, you have to be a giant to reach it. I ran new wires and installed addition light switches for the main houselights outside that box and much lower. My wife couldn't reach the house lights. We keep a 2 foot step ladder right inside the main door. 5er's have tall ceilings and tall cabinets, but it makes no sense why the light switches have to so high.
