A waterproof lampholder is provided. The lampholder comprises a lamp receptacle and a cap member. An annular extension is formed at an internal wall and adjacent a trumpet opening of the lamp recceptacle engageable with an outer periphery of a bulb for preventing external water from permeating into the forward end of the lampholder. An inverse V-shaped annular projection is in the bottom of the lamp receptacle aligned with a V-shaped annular groove formed in the inward surface of the cap member for preventing external water from permeating into the rearward end of the lamp receptacle. A pair of slotted projections on the cap member is aligned with a pair of M-shaped slots in the bottom of the lamp receptacle to define a pair of juxtaposed circular spaces for receiving a two-ply electrical cable which also provides waterproof function. Upon this arrangement, the present invention will no longer be causing an short circuit or an electric shock while raining or using a sprinkle in a yard.
