Tiring of recharging and battery life-spans.

I'm using a Schmidt SON hub dynamo, an E delux headlight ,
and a Busch and Muller taillight wired thru the headlight.

Have a E6 secondary and primary halogen lamp pair, FS, my last winter used.
they are such that you would kick in the 2nd lamp when the speeds are high enough
and double the illuminated area , ahead .

the halogens will draw what they want, I had a 5 D cell flashlight battery pack,
used a Union reflector in the 80s. It was fine for an hour long commute..
