The night puck has a median plane contiguous with a circumference thereof. The centroid of the puck is located at an intersection of the axis of rotation of the puck with the median plane. A cylindrical cavity extends therein along the natural axis of rotation. This cylindrical cavity has a thin membrane-like bottom wall. A series of holes extend radially along the median plane from the cylindrical cavity to the circumference of the puck. An electronic module is mounted in the cylindrical cavity. This electronic module comprises a battery and has a center of gravity that is located on the centroid of the puck. A push-button switch is held against the membrane-like bottom wall for operation of the switch by a depression of the membrane-like bottom wall. A series of diodes are mounted in the radial holes and are connected to the electronic module, for illuminating rays of lights around the puck.
