An internally powered, e.g. battery powered, emergency exit sign for an aircraft is provided which is portable and provided with an adhesive layer 3 to enable the internally powered sign to be adhered to a surface. An aircraft cabin requires cabin emergency exit signs which are electrically illuminated using an aircraft electricity supply. However, in the event of the failure of one of these cabin emergency exit signs, the internally powered sign may be adhered in the vicinity to act as a temporary replacement. In this way the flight worthiness of an aircraft may be maintained by a method involving the temporary replacement of a failed cabin emergency exit sign by an internally powered emergency exit sign.
