No idea. Not enough info.

all 12v systems are working except porch and bedroom lights

well, you need to provide more info.

are you hooked up to shore power or only on battery power?
are other 12v items, in the trailer, working?
have you checked the fuses in the panel?

Inside front and outside....

If you mean the light over the dash and headlights, marker lights and such (Assumesmotor home) Chassis battery isdead.

If you mean lights inside and outside the house part of a motor home, or on a trailer (Porch light as opposed to marker, Fuse or dead house system.

Find your DC Distribution Panel........usually part of the AC Distribution Panel
DC Fuses for lights, control circuits of fridge/water heater, furnace.
The fuses are probably not marked so you will need to test them.

Also check the light fixtures...may sure the on/off switches on the fixtures are ON.

By 'outside' lights I take it you mean porch/scare lights and not trailer running lights.
If running lights.they only work when hooked up to tow vehicle.
IF it's the trailer running lights post back for more info.

If other interior lights are working, it's probably a fuse, or a loose connection.
