Wayfinding apparatus for aircraft are disclosed. An example apparatus includes a wayfinding apparatus having a core composed of a light transmissive material. The core has a first surface defining a first face and a second surface defining a second face. The second face is oriented non-parallel relative to the first surface such that a second edge of the core is in a rearward direction relative to the first face. A transition is positioned between the first surface and the second surface. The transition is to optically couple the second edge and the first face.
