Abstract: Hideaway holiday lighting systems comprises a retractable bar for hanging holiday lights assembly. The retractable bar assembly includes a plurality of strings of holiday lights attached thereto; and at least one hinge mechanism coupled to the retractable bar permitting the retractable bar to be manipulated between concealed-up and display-down positions. The retractable bar is removably secured behind rain gutters and fascia boards of a building for automatically displaying of the plurality of strings of holiday lights when in the display-down position. The hinge mechanism is able to be repeatedly manipulated by a user between the display-down position, for at least one display-use during the holiday season thereby displaying the plurality of strings of holiday lights for illumination-decorative purposes, and the concealed-up position thereby concealing the retractable bar for the remainder of the season in a non-use environmentally-protected location.
