a submersible vehicular lamp assembly comprises a base plate , an elastomeric lens base and a lens body . a lip member extends from lens body side walls and is snugly received within a groove formed in a surface of the elastomeric lens base to form a sealed , watertight inner cavity . a light bulb is resiliently mounted in the inner cavity to dampen the bulb from road induced vibrations , shocks and the like . associated wiring for the lamp assembly passes through apertures in the lens base which are smaller than the thickness of the individual wires to prevent entry of water , dust , and other damaging elements .
