Abstract: A decorative lighting assembly comprises a first power wire electrically connected to a first power contact and a second power wire electrically connected to a second power contact. The first power wire and the second power wire cooperate to surround a display area of the decorative lighting assembly. Lamp assemblies are distributed across the display area. The lamp assemblies include a first row of lamp assemblies aligned along a first line, a second row aligned along a second line, a third row aligned along a third line, and a fourth row of lamp aligned along a fourth line. A first cord is disposed along a first zig-zag path connecting the lamp assemblies in the first row with the lamp assemblies in the second row. Intermediate wires are disposed along a second zig-zag path connecting the lamp assemblies in the second row with the lamp assemblies in the third row.
