ABSTRACT:
A light source includes a lamp and housing. The housing has a right-angle form with a first leg for the lamp, a second leg for connecting leads for the lamp and a jointure between the legs having an aperture allowing access to the connecting leads and lead-ins. The aperture has a bottom containing openings for the lamp leads-in and a contiguous sidewall containing openings for the connecting leads. The lead-ins and connecting leads are attached in the aperture to form lugs. A cover for closing the aperture has an area matching the area of the aperture and has outer and inner surfaces. The inner surface has a central boss and depending flanges that, when fitted into the aperture after a sealant has been dispensed therein, the boss extends between the lugs and the flanges extend outside the lugs, serving to displace the sealant and force it to surround the lugs.
