I have a few pictures of deuces with amber headlights in service, see below.
I myself managed to get hold on two amber sealed beams made by Westinghouse, which AFAIK are still to be bought in the States when you search by the Westinghouse number code. Only drawback: they are 12 Volt types.
They have an imprint on the back which says: "Not legal for highway use in the USA", which I thought was funny. I mean, a light, either it's roadworthy or not.
I probably won't use them because sealed beams are forbidden here. Another more suitable choice would be to find original Bosch reflectors with amber glass, which are on sale now and then.
Cheers,
Mark
