A vehicle, in particular a railway train carriage, is provided with a sequence of regularly spaced apart images 141-149 that form an animation when the vehicle is moving. An illumination system illuminates the moving images in sequence. The illumination system comprises a flashing / strobing light source (200, Fig. 2) which illuminates an image area 135 of the vehicle when that image area is within a defined location relative to the position of the light source and does not illuminate it when the image area is outside that defined location. A detector may be provided for detecting when the image area is in the correct position. The light source may be infra-red and the images may be reflective to infrared light. |
