We reproduce this square light diffuser for our customers with 1967-1971 Airstreams. It is also used on early 1970s Streamlines. Click on the thumbnails to see if your light base is the same.

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

Our diffuser is injection molded from strong, heat-resistant polypropylene. And it even features the original vent holes around the switch. It fits on the original base using your original rotary switch and requires no trimming or modifications. It will make your fixture look brand new.

We recommend switching to LED bulbs to dramatically reduce battery draw and reduce heat build up.

Please note we also carry a switch that we recommend for this fixture. It is our VTS-432. It works well but unfortunately does not allow you to reuse your original plastic knob.
