In my mind, all of the items/lights required to operate the bus as a vehicle on the road should be part of the bus/chassis electrical system. Everything else is the "house" electrical system.
To this end I have stripped all the interior lights from the vehicle system, and they will go back in on the house system
The one interior light that will go back in on the vehicle system is the driver's dome light.
Even with the ignition "off", the clearance lights, and front and rear marker lights come on when the headlight switch is moved to the 1st position, so they can stay as they are. They will all be LED anyway and they can be on for hours without hurting the starting batteries.
