The 'E' means e-code, but there are several varieties. Guessing that also on the lens is an H4,
which is one of the types that will fit in the sugar scoop. There may be a sticker on the back w/ E2 and H4 on it.

In the US, the cars were imported with sealed beam headlights in Sugar Scoops that were DOT approved.

The DOT refers to the lens, not the light. None of the e-codes were officially approved by DOT.

There are other H4 lights that do not fit in the sugar scoop - the ones that most people here call H4's. There are also H1's that look a lot like them, and H5's that also look a lot like them.

H1's are generally regarded as the best (most expensive, too and no longer made).
H4's (both kinds are next).
H5's next
Sealed beam last.
