1. An aircraft provided with a light signalling system comprising:
at least one light-emitting device at a tip of each wing; and
at least one light-emitting device at an end of a tail, each light-emitting device at the wing tip being disposed in a hollow provided in a profile of the wing and comprising a lining, at least one light source and a protective cover disposed on the hollow so that an exterior surface is flush with a shape of the wing,
wherein an interior surface of the protective cover is provided with at least one localised variation in thickness so as to increase an angular spread of each light-emitting device at the wing tip in order to ensure overlap between the light emitted by the light-emitting devices located at the wing tip and
the light emitted by the light-emitting device located on the tail, the protective cover has a variable thickness so that the interior surface of the protective cover substantially matches the shape of the hollow, in order to minimize a distance between said interior surface and the at least one light source, wherein the hollow has a three-dimensional shape, and the interior surface of the protective cover substantially matches the three-dimensional shape of the hollow.
