Abstract: Containers or closures, preferably for liquids, are provided having means for holding a light source for illuminating the containers, preferably the interior of the containers. The holding means can be associated with any portion of the container, including its closure, body, side wall(s), handle, or bottom, which can include a base portion or bottom extension. The holding means can include an opening defined by a ledge in the closure, or it can include a housing which can extend upwardly or downwardly from the closure, or bottom or bottom extension. At least a portion of the container which is between the light source and the interior of the container is a least partially transparent to light.
