FIG. 1 is a plan view of a soft flexible sheet of amber colored transparent vinyl comprising a fog lens in accordance with this invention having a peripheral configuration matching that of a rectangular headlight lens of an automobile.

FIG. 2 is a perspective view of an automobile headlight with the soft, flexible fog lens of FIG. 1 shown in position for affixing to the headlight.

FIG. 3 is a front elevation view of an automobile headlight having a soft, flexible fog lens in accordance with this invention affixed thereto.

FIG. 4 is a section view taken on line 4--4 of FIG. 3.

A fog lens in accordance with this invention comprises a soft, flexible sheet of amber colored vinyl 1, available commerically as matt vinyl and having a thickness of about six mils, which is cut into the peripheral outline shape of an automobile headlight 2 or other lamp on which it is going to be used.

In the drawings, the type of headlight shown is a rectangular sealed beam headlight in which the glass lens 3 has three projections 4. To fit this headlight 2 and enable the facing surface of the soft flexible sheet 1 to come into close contact with the glass surface of the glass lens 3 throughout the entire mutually facing area, the soft vinyl sheet 1 has three corresponding apertures 5 located for registration with the 3 projections 4 of the glass lens 3 where the soft vinyl sheet 1 comprising the fog lens is put in place over the glass lens.

The soft vinyl sheet 1 is pressed firmly against the glass lens 3 to squeeze out any excess water and to remove any air pockets.

The fog lens soft vinyl sheet 1 will stay securely affixed to the glass lens 3 of the headlight 2 when put in place as described above, and will remain affixed while driving great distances and for substantial periods of time.
