Abstract
Abstract A ski pole has a tubular body member having an upper end portion of enlarged diameter to provide handle means and a removable cap at its upper end. A cylindrical chemiluminescent member having an enlarged head portion is disposed in said body member with its head portion seating against an internal ledge at the lower end of the handle means. An opening in the wall of said tubular body member emits light from the chemiluminescent member. In a further embodiment a dry cell battery is disposed in the upper end of the body member and includes a pair of probes connected to the battery terminals and adapted to be projected downwardly through the upper end of the chemiluminescent member to re-energize the same.
