The lamp bodies andfronts are made entirely of pressed steel, which materi-ally reduces the weight and improves the appearance ofthe headlights. The makers have taken advantage ofthe accuracy with which steel stampings can be madeby producing a headlight which is water and metal ring which holds the reflector in place alsoclamps a heavy gasket over which the front or doorpresses, making a very tight joint.
