ABSTRACT A moveable pointer (15) on an indicator (11) is illuminated by use of at least one electroluminescent strip (21) which is mounted separately from the pointer (15). The pointer (15) is able to conduct light inter- nally in such a way that light transmitted to one por- tion (23) of the pointer (15) illuminates another por- tion of the pointer (25) The electroluminescent strip (21) forms a light source for the pointer (15) so that the strip (21) may be mounted adjacent the pointer's hub (23) in order to provide the necessary illumination. This arrangement permits an indicator (11) to be illu- minated with electroluminescent lighting in order that passive vision aids, such as night vision goggles, may be used, while providing sufficient illumination for the indicator's dial pointer (15).
