ABSTRACT:
A mechanism for improving the installation and access to the interior of large illuminated signs and lightboxes is disclosed. A plurality of rotatable arm members are connected between light modules mounted on a building or wall surface and a removable front panel module. Mating pairs of brackets hold the two modules together when they are coupled. In order to gain access to the interior of the lightbox, the brackets are disconnected and the front panel module is rotated via the arm members to another position adjacent the light module.
