A portable navigation light system for barges in which the legally required three lights are provided by a set of three, self-contained units. Each unit contains its own power supply, light activating machanism, light source so configured as to show over the required arc of the horizon with the required range of visibility, and means for affixing the unit to the barge. Each unit incorporates an integral carrying handle and is configured so that the three units nest one inside of the other with their respective handles coinciding as one, thereby permitting the carrying of the nested units as one.
