Abstract: A ski attachment device having safety, functional and decorative features. The ski attachment includes a sheath adapted to be retainably received over the tip of the ski, a battery-powered light, and a housing for mounting the light on the sheath so as to aid a skier during periods when sufficient illumination is not available. The ski attachment device is particularly useful in alpine and cross-country skiing to illuminate the trail in front of the skier, to assist the skier in always knowing the position and alignment of his ski tips, and to aid other skiers in being able to see the position and direction of motion of the skier. A hood-like extension at the forward end of the housing directs a major portion of the generated light in a forward direction and an aperture in the extension allows a smaller portion of the light to be directed rearwardly and upwardly for alignment purposes.
