A self-contained lighted marking device that is a directionally dependent line light source has a substantially transparent housing. The housing has a narrow cross-section, preferably rectangular in shape. A thin, flexible film having a smooth surface on one side and a plurality of linear substantially right angled isosceles prisms on the other side is located along the periphery of the interior of the housing. A light source, preferably a plurality of light emitting diodes, are located at at least one end of the housing.
