We've had this inside light cover made for our customers with 1967-1971 Airstreams.  It is also used on early 1970s Streamlines.   Click on the MORE PHOTOS button to see if your light base is the same.

It measures 6-3/4" square and fits inside the edges of the base.

It is made of strong, heat-resistant Lexan® polycarbonate, rather than the original low-grade plastic which melted in the heat. It is the only replacement available that fits on the original base using your original rotary switch and requires no trimming or modifications.  It will make your fixture look brand new.

You may want to drill vent holes in to match the original to further enhance ventilation to the fixture.

Please note we also carry switches for this fixture.
