You have a blown fuse or 12 breaker, which ever one your rig has.
Just looking at fuses is not 100% as some blow on a part of the tape that you can't see. You have to test the output side of the fuse to be sure.
Breakers usually show some indication that they have blown. A slight mis alignment with the others is often the indicator.
Since the bedroom lights are on a separate 12 volt
circuit and blew a fuse you may have a pinched wire or weak fuse. If once reset it blows a fuse again you have some inspecting to do to find the reason. If it is a breaker and blows again swap the wire with another breaker and see what happens. Breakers can be weak also and if this is the case it has to be replaced.
