Abstract: An improved assembly of rectangular frame carrying a strand of inward-pointing Christmas tree lights includes a shoulder in the inner end of each hole for a light, limiting inward travel of the light on simple assembly in which the lights and sockets are pushed through from the outside; for instant assembly/disassembly an elastomeric band around the outer perimeter in a groove in the frame retains all lights and can help retain the assembly in a window frame, if desired, together with one or more plunger type retainers.
