Vista light This system is used to create freestanding, convex, double sided signs, or wall mounted signs, that can be backlit with the addition of interior illumination, or used with standard sign substrates without illumination. Vista light is designed to accept standard signage substrates. Great for show rooms, lobbies, displays, parking garages, advertising, point of purchase, shopping malls, trade shows etc. This cost effective system is constructed from two special aluminum extrusions, an end cap, face inserts, and a base, for either portable, or permanent installation. The only tool needed for assembly is a screwdriver.
