Abstract: An icicle attachment for a light bulb which includes a hollow tube having a shape simulating a pendant spear of ice. The tube is tapered and receives a standard string light bulb with two radially inwardly directed spokes for enabling a bulb socket to be inserted therepast and thereafter retain the bulb socket in the tube top. Slits formed in the walls of the tube proximate the open body and communicating therewith enhance water drainage from the tube and light escape or sparkle of the icicle attachment.
