In an aspect, an apparatus is provided and includes an air-tight object having an outer layer, an inner layer, and a cover, and a light module. The opacity of the outer layer is greater than the opacity of the inner layer. The outer layer defines a first aperture and a second aperture. The inner layer and the cover define a first interior region. The inner layer defines a second interior region. The light module is encapsulated within the first interior region and is configured to send light through the inner layer, through the second interior region of the air-tight object, and through the second aperture of the outer layer, wherein the cover is disposed between the light module and the outer layer.

A light-emitting golf ball using a small generator includes a core that is a center point of the golf ball; an inner shell formed to surround the core; an outer shell formed to surround an outer surface of the inner shell and struck by a golf club; a generator positioned on one side of the inner shell and generating a current based on a rotational force caused by a stroke; and a light emitting portion located on one side of the inner shell and providing light so that the golf ball emits light based on the generated current. According to the present disclosure, the golf ball emits light, and thus it is easy to track a trajectory of the golf ball. In addition, it is possible to more easily determine the trajectory and position of the golf ball when the day is cloudy or enters the night.

An illuminated pickleball contains an elongated LED illuminated element with two opposing ends and comprises a shell that includes a plurality of apertures therethrough, two of which being designated as access aperture. The shell includes two opposing element holders which each include a shank projecting inwardly from the inside surface at one of the access apertures and which are mutually longitudinally aligned through a center point of the shell. Each holder is adapted for receiving the elongated illumination element and for retaining one of the opposing ends of the elongated illumination element by friction. When one end of the illumination element is inserted through an access aperture and then through one of the holders to engage the opposing holder, the opposing end of the elongated illumination element is retained, and the illumination element traverses through the center point of the shell and illuminates the pickleball from within.
