A method for making an electroluminescent marking on an exterior wall of an aircraft, including a step of superpositioning of layers designed or configured to produce the electroluminescent marking on a first face of a flexible backing distinct from the aircraft to obtain a marking tape and a step of affixing the marking tape to the exterior wall of the aircraft. The disclosure herein also concerns a marking tape for the implementing of the method, a marking device obtained from the method, and an aircraft comprising the marking device.

A lighting system for air mobility may include a light emitting unit provided on a boom or a propeller of the air mobility and configured to emit light toward a ground surface so that the light is projected onto a point directed toward the ground surface from the propeller or the boom; and a control unit electrically connected to the light emitting unit and configured to control light emitting modes of the light, emitted by the light emitting unit, based on operating modes of the air mobility or operating modes of the propeller.

Example implementations relate to decorative display panels for aircraft interiors. An example display panel can include a display shell having one or more openings arranged to form a decorative design and a translucent layer coupled to the display shell. The translucent layer can extend across the openings in the display shell. The display panel can also include a lighting interface coupled to the translucent layer and configured to illuminate one or more portions of the translucent layer positioned relative to the openings in the display shell. The display shell may be coupled to the interior panel such that the translucent layer and the light interface are positioned in between the display shell and the interior panel from an aircraft. In some examples, the lighting interface can illuminate the display panel using different colors and patterns based on desired visual effect and/or operational status of the aircraft.

There is described a vehicle color-lighting control system. The system comprises at least one sidewall (101) having an electrically-controllable coloring mechanism (106) embedded therein and arranged for coloring at least a portion of the at least one sidewall with at least one first color; a lighting sub-system (110) comprising at least one light source (112) mounted within the vehicle to illuminate an interior of the vehicle with at least one second color in a first state and with at least one third color in a second state; and a controller coupled to the coloring mechanism and the lighting sub-system and configured for operating the coloring mechanism to color the at least one portion of the at least one sidewall with the at least one first color and concurrently illuminate the interior of the vehicle with the at least one second color.

A warning tag and process of making the warning tag are provided. The warning tag has a substrate layer, a reflective layer laid on top of the substrate layer, and a negatively printed message on the reflective layer. In some embodiments, the reflective layer is covered with non-reflective ink to form the non-reflective ink coating such that a warning indicia message is left exposed while the surrounding area thereto is covered. A process of making such warning tags is also provided.
