An illuminatable sign includes a number of lighting modules arranged on an electrical circuit such that they are individually disconnectable, removable and adjustable in position between conductors. Preferably the lighting modules are slidable on the conductors while remaining in electrical contact to provide illumination where it is specifically required. Connections between the modules and the conductors may be such that the modules slide on the conductors. Such connectors may be snap on connectors or may be prongs insertable into helical springs about the conductors such that compression of the springs increases the diameter of the springs to allow them to slide on the conductors and lack of compression allows the springs to grip the prongs tightly.
