The dynamoregulaor LED bulbs have two LED's, one either side of a blade, one for dip two for full beam, so very hard cut-off. I have not played with the focal length of the bulb position on the prewar bike, reflector is not good on that bike, The combination works fine for a 1937 bike, a vast improvement on what I had out of a standard BA15d bulb from the limited dynamo power.
1961 A10SR, spent a fortune at SRM
1961 A7SS, finally the right green
2011 New addition 1937 Empire Star, twin port, high pipes. Turned out to be the most unreliable bike I have handled.
2017 finally found the liner/barrel were flexing and causing all the overheating/nipping up. Early B33 barrel fitted and it's reliable at last!

The LED bulbs I bought for my bike were happy with any voltage from 6-24v but were specific on polarity. For me they remove the argument about voltage although with good wiring and clean reflectors my 6v bike was indistinguishable from the 12v one in light brightness

 That's handy partial info....what breed of insert and  reflector are they ?

 One Thing I have trouble with is colour (which is easily worked out),and 'stated * lumens*'  *conf2* which means farqueall really- it depends on how the 'lumens' are calculated...then there is 'Lux' which I think is more relevant....depending on the situation *pull hair out*

G'day Woz.
Could end up a bit confusing. Make both the same earth. I did.

How does one vote - or has the poll closed? Don't tell me someone is reading all the posts and filling in a spreadsheet!

'Scroll back up to the top of the page'

Already looked there for a while, but can't find a way to vote. What am I missing? Maybe poll is now closed.

bsaBill - not me I'm afraid. All I see is the poll result, but no means of casting a vote . But never mind, it's not important and I know when to give up.
Re the 6v debate; all my 6v vehicles - including a T20 Ferguson tractor - have stayed on 6v. After all, we're talikg wattage for lights / horns etc, and when using 6v instead of 12 that merely means twice the amperage for the same result. Provided the wiring is suitable, there should be little or no difference. For electric starting there can be a difference, as discharge rate is proportional to battery plate area, and 12v batteries usually have greater surface area meaning, on a tractor (or car etc) you may only get say 200A x 6v compared with 300A x12v. Just when you need more, you get less. But then few our bikes have been converted to electric start and the modern ones (eg my firestorm) are 12v from new.

That’s weird... normally once voted it should disappear. Otherwise it would be possible to vote a million times if you wanted. Haven’t changed your PC or something?

looks like I'm in a virtual Tardis maybe, with option to freeze time

No actually I wondered if it was an unknown feature of Firefox (it has a few) so I've just tried it in Edge and Chrome - comes up just the same, possible to do with the way I open the tab (goes straight to recent posts?), I have tried to see if I could vote again and yes I could if I then pressed sumbit  , which I didn't

On this Android tablet I do not see the voting buttons; only the results.

Difficult choice. The A10 is 6 volt and sticking with it, the A7 is 12 volt and sticking with it. I would say that if you have a decent 6 volt system (separate earth wires make all the difference), why change? If you need a dynamo overhaul, why not go 12 volt?
