1. A remote indicator system for enabling a signal to be sent from a first location to a second location, the system comprising a housing located at the first location and a display unit located remotely from the housing at the second location, the housing comprising a first light source which is electrically powered and illuminated, and a first end of an end-emitting fibre optic cable; wherein a second end of the end-emitting fibre optic cable is located within the display unit;
wherein the housing includes manual switching means having at least two states, including: a first state in which light from the first light source is allowed to pass into the first end of the end-emitting fibre optic cable and light is transferred to the second end of the end-emitting fibre optic cable, providing a visible indicator light on the display unit; and a second state in which light from the first light source is prevented from passing into the first end of the end-emitting fibre optic cable, and light is prevented from transmission to the second end of the end-emitting fibre optic cable, such that the indicator light is not illuminated on the display unit;
and wherein the manual switching means is operable by an individual at the first location and allows the individual at the first location-to switch on and to switch off an indicator light on the display unit without completion of an electrical circuit such that the indicator light on the display unit is viewable by a second individual at the second location.
