For vintage, I have a Union dynamo/headlamp block unit on my '53 Rudge Sports. Still works good, though needs frequent adjusting. This was gifted to me by a friend in NY.



For modern, on my '84 Raleigh Crested Butte I have an AXA HR bottle unit gifted to me by a friend in the UK (a pattern?), coupled with B+M LED headlamp and taillamp. This set-up works really well.
