Sierra? spotlights on my 41 Four

[kustomizer]

I was told they came on the bike from the factory and they look like the ones in the "Indian Motorcycles 40th Anniversary Sales Brochure". They are not in very good shape as the old guy I bought the bike from was still trying to ride it in his mid 80's, it was too big for him when he was 50 but he had it, liked it, and wanted to ride it more than anything but "the damn thing keeps falling over when I stop" was his main complaint. Anyhow from those of you that know, are these the factory accessory "Sierra" spotlights that could have come in it? Is there any known source for parts for them?
thanks for looking
