Modular decorative light system
A sculptable, decorative light system includes a number of modules of differing lengths which can respond to commands either in parallel or time delay to create pre-selected light colors and sequences. Three miniature connectors are used to create a direct current fed system which has the potential to even out a current demand. Interconnectable lamp modules are provided in sets of 1, 2, 3, 4, and more lengths to create decorative light displays. Each lamp module or string of modules may include a male/plug end and a female/receptacle end.
