Abstract: The illuminable address display system may include mobile support blocks adjustably connected to each other. An anterior side of each support block may have an illuminable transparent number. The system may further include a plurality of conductive cords, with ball bearings attached directly to first and second opposed ends. The cords may adjustably connect adjacent support blocks and the first conductive cord may connect to a power source. Each support block perimeter may also includes a track with a plurality of sockets running along the thereof. A conductive coupling may be seated within each support block and electronically coupled to the track. The conductive couplings transmit electricity from the power source, along adjacent conductive cords, and to a light-emitting member in each support block. A controller may be coupled to the conductive cords for toggling each illuminable number into off or on modes.
