Known emergency exit signs are static and are unable to adapt to an emergency and indicate safe evacuation exits or routes where some exits may not be available. An illuminated sign comprising a body including at least one display surface, a first member having opposite inner and outer faces and a peripheral edge that interconnects the faces of the member. The display surface being formed at or over the outer face of the first member. A first light source being arranged to edge illuminate the first member. The first member incorporating a light dispersive medium arranged to illuminate the display surface with a first display through illumination of the first light source. The body further comprising a second member being disposed in face - to - face relation with the inner face of the first member. The second member being formed from a plurality of sub - members. The plurality of sub - members including a first sub - member positioned adjacent the first member. A second sub - member including a second light source being in the form of a light array arranged to project light through the first member towards the display surface. The light array being able to be illuminated in one or more patterns to generate at least one pictograph that forms at least one second display at the display surface. The first sub - member being in the form of a stencil which focuses the second light source. The sign is configured such that the at least one second display is selectively displayed on the display surface in response to an illumination condition of at least one of the first or second light sources.
