Schmidt hub dynamo, E6 halogen bulb headlight , B&M 4D topmount rear light.
Now, 2 bikes, recently placed the battery operated rear light, on my BikeFriday,
that came off my Koga WTR, Tubus Logo rear rack,..
when I added a wired into the headlight ..one in its place..

Clever kludge: , I made a light mount for the 2 bolt Euro taillight,
that was fitted onto the low, rear of the seatpost water bottle cage,
[used Zefal mudguard struts, for the project]

So as to not cover my lights with my Rain Cape ,

when I ride thru the Downpour.. North Pacific Coastal storms do that ..
