Abstract: A housing assembly includes a combination lens and window retainer, an inner optical lens, an outer optical window and a front cover. The retainer includes a middle body structure, a pair of side wing structures, an inner seat and an outer seat. The middle body structure has opposite lateral sides, interior portions and exterior portions. The side wing structures are attached to and extend in opposite lateral directions from the opposite lateral sides of the middle body structure. Each side wing structure has exterior portions. The inner seat is defined on the interior portions of the middle body structure. The outer seat is defined forwardly of the inner seat on the exterior portions of the middle body structure and of the side wing structures. The inner optical lens is mounted to the inner seat of the retainer. The middle body structure and side wing structures together define an opening aligned with the inner optical lens and provides an unobstructed forward panoramic field of view through the retainer.
