A is the diamond-shaped body, and B B the prisms thereon.     I have shown certain angles of the prisms and certain angles of the body of the light; but the essential features of my invention are found in a prism-light of a diamond shape with prisms across the same substantially parallel to its short axis.     I claim--     The design for a prism-light substantially as shown and described.
