I have had excellent outcomes using Autopal replacements. It is a completely metallic light with a glass lens, manufactured in India. I have used them in BMWs, Triumph TR6, and my MG Midget. They were formerly readily accessible, but are no longer as easily found, at least not in the United States. One factor to consider while purchasing new lenses is the lamp's facade. Some are flat and do not correspond to the appearance of the original sealed beam lights.
