Abstract: A support frame for decorative lights disposed about a window includes top, bottom, and first and second side members connected together to form a generally rectangular structure. Each frame member includes a pair of elongated, linear members connected lengthwise in a telescoping manner which are hollow and rectangular in cross-section and have respective inner and outer walls. The inner and outer walls of each frame member are each provided with a plurality of spaced apertures, with each pair of aligned apertures in the inner and outer walls adapted to receive a decorative light in a tight-fitting manner. Lights inserted in aligned apertures of a pair of telescoping frame members prevent sliding movement between the frame members. This telescoping connection within each linear frame member in combination with a spring-biased tension cap on the end of each frame member allows the support frame to be adjusted to fit a wide range of window frame heights and widths.
