An underwater lighting apparatus includes a lamp having a filament, an envelope surrounding the filament, and a pair of contacts extending through the envelope, and a wiring arrangement for electrically connecting the contacts to a source of electrical power. The wiring arrangement includes a socket assembly on which the lamp is removably retained through a friction fit connection between the contacts of the lamp and a pair of terminals of the socket assembly and includes a transparent casing having an open axial end and a closure member retained in the open axial end. The closure member may be removed from the open axial end of the casing to permit replacement of the lamp in the socket assembly.
