Abstract

Abstract A waterproof coupling for use in conjunction with illumination systems for swimming pools, spas, and the like, employs a light conduit placed within the waterproof fitting to provide safe light for underwater use by keeping any source of electricity remote from the water. Some embodiments may be removed from the pool. Others are permanent.
