The same fuse controls power to the parking lights, the tail lights, and the dash lights. That circuit is designed that way on purpose- - - -if the dash lights go out, it also means you don't have any tail lights. Do the tail lights burn with the light switch in the "headlight" position, or does that also blow the fuse? You might start looking for mouse-chewed wiring under the dash- - - - -it's a problem that's pretty common on vehicles that have been parked for a long time.
