Abstract: A longitudinally curved, modular housing assembly for the protective support of illuminated glass tubing, such as neon lights, characterized by interconnected base, central, and cover sections which are all curved and have equal radii of curvature. The configuration of the housing assembly is such that it permits combination thereof with other, similar, housing assemblies to provide continuous lighting systems having various shapes and outlines. The housing assembly preferably contains a transformer and wiring for connection to a power source.
