ABSTRACT:
An electrically lit chess piece includes a chess body which is coupled to a transparent cap at the top end and contains an internal battery housing. The battery housing includes a bulb positioned under the transparent cap and a magnet having springs at the bottom section. When the chess piece is placed on a metallic chessboard, the magnet is displaced in a downward direction and the bulb is lit. When the chess piece is removed from the chessboard, the magnet is pulled in an upward displacement by the springs and disconnects an electrical circuit for turning the light bulb off.
