I imagined uranium glass lenses with UV lamps when I saw this topic, but these are quite cool.
Also worth reading the photo captions for a bit of suspect translation, but they are using apostrophes correctly

Christine, did you notice the mention of a NOTEK car uranium headlamp, made in Britain? Bottom of page. I have seen NOTEK on eBay before, but not sure whether these were uranium glass.
... the shorter wavelength of light cut by the power transmission that because the UK is a lot like fog in the country was the right thing
Hmm, I think I know what they mean!
