Abstract: Disclosed is an underwater lighting apparatus securable in the transom drain hole of a vessel. The apparatus is formed from a support structure having a chamber for housing at least one LED or the like lighting element. An outer surface of the support structure is sized and arranged to sealingly secure to the transom drain hole of a conventional boat to prevent water passage. The apparatus includes an internal power source, namely disposable cell batteries or a rechargeable cell, for providing power to the lighting element.
