If you're looking for a rechargeable solar powered LED emergency light kit, then you surely can't go wrong with the Capsuli. Tiny enough to be stored, it offers performance that betrays its size. Each capsule is docked into a pad embedded with solar cells - you simply activate the light by twisting the capsule. Unfortunately, the Capsuli is but a concept at this point in time so we're just waiting around for some level-headed manufacturer to make the whole thing a reality.
