Vtg. Universal Lites Red Christmas Lights 15 Outdoor Set Length 18’ CA RD-1967

See photos for true size and condition. Open box, protective cellophane was barely intact and removed to test. I believe these have never been installed except for me testing the string. Box says RD-1967. I am unsure, but these may be from the 1960s? Box shows wear. One bulb tested to ensure cord is in working condition. Cord is labeled Universal Lite Christmas tree cord.
