if thats your CV, I'll just watch you work it out for your self .. robo engineer I'm not.


Seems bike lights have stayed 6v for a long time, I built a 6v battery pack using 5 1.2v D cells in series .. 25 years ago

bulb lights draw what they need from a battery , I suppose.. front halogen .. Union headlight reflector .. flange base bulbs came from Radio-Shack

had a 60 minute commute back then.
