An electronic apparatus such as a notebook PC or mobile telephone is provided with a badge comprising a multi-layer panel and a light source mounted within the body to illuminate the badge panel from behind. A control circuit senses the orientation of the part of the casing body controls the light source so as to activate it when body part is in a predetermined range of orientations. The multi-layer panel is designed to present a logo in a first orientation (relative to said body part) when illuminated by ambient light and in a second orientation when illuminated from behind by light source. By this means, the orientation of the graphic elements as viewed by an observer can be correct more of the time than by a conventional badge.
