Contoured headlight concealment lens

Claim 1

In a headlight concealment device for use in conjunction with a vehicle including a contoured body, the improvement comprising: headlights operably attached to said vehicle and disposed beneath said contoured body and disposed to selectively project light through an opening in the forward position of said contoured body; a transparent lens disposed over said opening and being attached to said contoured body such that said lens smoothly conforms to the contour of said vehicle body, said lens including an internal cavity that is co-extensive with and overlies said opening; wherein, the upper portion of the internal cavity terminates in a vacuum port; and, an enlarged area is formed in the internal cavity adjacent said vacuum port; an opaque fluid reservoir attached to said vehicle and disposed in fluid communication with said internal cavity; a ball disposed in said enlarged area of the internal cavity and adapted to move from a location spaced from said vacuum port to a position blocking fluid communication through said vacuum port; wherein, said ball has a specific gravity that is less than the specific gravity of the opaque fluid; and, means for selectively filling said internal cavity with an opaque fluid, thereby concealing said headlights when they are not in use; wherein, said means for selectively filling the internal cavity with opaque fluid includes means for applying a vacuum through said vacuum port to said cavity; whereby, the level of the opaque fluid within the cavity will cause the ball in the enlarged area of the internal cavity to float to a position blocking fluid communication through said vacuum port.
