Abstract
This invention discloses a lamp housing adaptable for snapped-in installation of the lens member. The interior wall of the housing is provided with an annular step and integrally formed raised projections which together form slots for receiving the peripheral edge of the lens member. The raised projections are shaped to facilitate the installation and retention of the lens. The lens member, made of resilient material, is of sufficient flexibility that it can be pressed past the raised projections and be lodged in the slots. A gasket is interposed between the lens member and the annular step. The slots are so dimensioned that the raised projections press against the lens and the gasket to retain the lens in the slots and additionally seal the interior of the housing from the outside environment.
