"The 'D' would probably have been the only Ni-Fe period RE"

Correct Rik! I have one on my WD/D and both my BSA KC10 and WC10. Ron

Early Maglites were only 4 volt so would need a 4 volt battery for its 8 watt headlight bulb.Later ones were 6 volt.

After riding with an 8 watt headlamp bulb the glow from a blackout mask must have made them feel quite at home...
Having ridden my bikes at night over Dartmoor many times (without any streetlights) but with a standard 6 volt Lucas set up I don't think I'd relish any less lighting..It's nearly impossible to see the sheep, cows, badgers, rabbits, foxes and ponies as it is!!....:milky_way: Ian

I was lucky to obtain a Nife regulator - bsa type

But after discovering my project bike was produced after it’s discontinuation- I am unsure what to do now - it was another nice feature along with the big battery I had wanted on my bike

Lots of good information in this thread
