A device for illuminating a vertical tail plane of an aircraft, comprising a matrix of LEDs or lasers, a laser diode with a diffractive optical element, an electronic board with a microcontroller, a power supply unit and a housing enclosing one or more of the matrix of LEDs, the laser diode, the electronic board and the power supply unit. The LEDs or lasers and the laser diode are individually and electronically controlled by the microcontroller, in such a way that the LEDs or lasers can be individually dimmed to create a dynamic illumination pattern on the side surfaces of the vertical tail plane. The illumination pattern is transmitted by the microcontroller. The laser diode with the diffractive optical element can create a fixed figure on the side surfaces of the vertical tail plane. An aircraft is provided with exterior illumination on its vertical tail plane, comprising such illumination devices.

An aircraft passenger service unit signage placard adapted to be retrofitted to a passenger service unit, the placard comprising at least a first signage area and a second signage area, wherein the first signage area is arranged to be illuminated by a switchable illumination means in the passenger service unit and wherein the placard comprises a first and a second layer and photoluminescent material is provided on at least one of the first and second layers of the placard in the second signage area, the second signage area having at least one first icon illuminated by the photoluminescent material such that the first icon is always illuminated in use.

An aircraft passenger service unit placard comprising an integrated unit adapted to be retrofitted to an existing passenger service unit having a bi-pin lamp connection, the integrated unit comprising at least a first signage area and having at least one low energy illumination means arranged to illuminate the signage area, wherein the low energy illumination mean is optionally an LED unit and wherein the integrated unit comprises a first layer and a second layer separated by a light guide and wherein the illumination means is arranged as a side light in the light guide between the first layer and the second layer, the integrated unit further comprising at least one flexible connector arranged and adapted to connect to the bi-pin connection.

A racing vehicle for providing dynamic advertisement opportunities includes a digital sign or digital signs mounted thereto. Digital sign(s) can present content in different manners. Digital sign(s) may receive content and instructions for presenting the content via a user interface or from an external device via a communication interface (e.g., wireless interface). Digital sign(s) include a mobile power source (e.g., battery, fuel cell, solar cell). Digital sign(s) may be preformed to fit on a specific portion of the racing vehicle and be secured to the body or frame of the racing vehicle in various manners. Content presented on the digital sign may be changed per event that the racing vehicle partakes in and thus provides additional advertisement opportunities for the racing vehicle. The racing vehicle is any type of competitive vehicle, including single wheel vehicles, two-wheel vehicles, four-wheel vehicles, tracked vehicles, flying vehicles and water vehicles.
