Abstract
Abstract A ski pole has a tubular body member with an arcuate or circular transparent or translucent insert in the wall thereof comprising a window element and a light source within the body member illuminates this window member and also projects light along the interior of the body member to an inclined mirror element at a lower portion of the ski pole. The light impinging on this mirror element is directed radially outwardly through a lens member fitted into the wall of the ski pole so that reflected light from the mirror is projected outwardly to illuminate the surrounding terrain.
