This vintage set of bar lights is a string of seven lights on a long 156 inch electric cord.  All are in very good working condition and the plastic imitation "cans" are identical to the real metal Schlitz cans.  The seven heavy plastic light covers measure 5 inches in height and have a crisp Schlitz logo on the front and back.  A round hole in the top allows a small bulb and receptacle to be inserted there, connected by a long green electric cord.  One end has the electric plug and the other end allows other cords to be attached if desired.  This is a unique find for the bar or man cave and probably dates to the 50's or 60's. Thank you for looking.
