A probe extends from a two-part plastic housing. The first part has an externally threaded cylindrical section, which is adapted to mate in screw fashion with an internally threaded cylindrical section of the second part. A member is inserted between the parts and includes a cylindrical portion, receivable within the threaded section of the first part for structural reinforcement of the housing, and a flange, positioned adjacent the rim of the first part, to properly locate the member. In one embodiment, the first part and the member are provided with oppositely directed slots which align to form a radially extending channel through which a lead extends. The sides of the channel engage the lead to provide strain protection. A spare bulb mount is provided on the member and extends into a cavity formed in the second part. In a second, self-powered, embodiment, the structure of the member is modified to eliminate the bulb mount to permit a battery to be received within the cavity of the second part.
