got it .. almost... Schmidt dyno hub, and an E6 headlight, halogen ,
have a 3w bulb in the one without a taillight , [and a battery blinkie taillight, on the seatpost]

and, a 2.4w bulb when I had the tail-light wired in. [0.6w load]

Super-Novas or an Edelux LED healight can be considered,
which I may up tick a bit to, improvement.

yes, German lighting does not blink, due to their regulations at home..

only exception is the senso mode in the B&M topmount rack taillight,
in a tunnel situation, going from daylight to dark and back,
it will blink in a slower repetition. in the dark.
and for a while in the dark after you stop.. a movement detector is in there.

standlight modes, include a capacitor rather than a rechargeable battery
