I have adopted a hub dynamo light system,
there are nice practical lighting systems that can be assembled.

.. made in Germany NL, and of course, Asia.
what's your budget?

Hub, Schmidt, lights, Busch and Muller or Schmidt
I have a Halogen bulb headlight , and an LED taillight, now.

may get a B&M Lyt it's a modest priced LED headlight, for Dynamo power.


have had for years, ..
An external battery pack from Nightrider, [San Diego Cal]
with a 10w halogen bulb is great, nice and bright.
the Sport set uses a 5 D cell battery pack , screws closed watertight,
they also use it as a Dive light.
