Abstract: A vehicular lamp having a one piece open topped resilient housing containing an outer peripheral groove that permits the housing to be snapped into a receiving opening formed in a body panel of a vehicle. The housing further includes an inner peripheral groove located above the outer groove into which a lens is snap fitted to close the housing. The inner groove is offset from the outer groove a sufficient distance so that the lens can be removed and replaced without having to remove the housing from the body panel. An outwardly disposed lip protrudes from the top of the outer groove that is inclined downwardly over the groove opening so that it will form a biased seal against the rim of the panel opening when the lamp is snap-locked in place.
