I did search the forum and I think I have the best answer, but I want to make sure.
I bought a 1953 Raleigh Sports over the weekend with a lovely, working generator light. It is, however, too dim to depend upon. I was thinking of getting a new hub-powered light, but the mechanic suggested I just look for an LED bulb that would fit the housing (it is all in really good order). From the archives, I found this site:

And I am planning to order an LED bulb from them. Is this the best plan if I want to keep the light as is? It seems the technology has changed so much in the last few years...
