ABSTRACT:
An illuminated sign (2) comprises a sign panel (5) and at least two elements of electroluminescent material (14, 15) each element being individually selectively actuable and arranged to emit light so as to illuminate the sign panel. Each element may be used as a photodetector or a photo-emitter. A retro-reflective strip (10) may provide additional visibility.
