Scalyback - re Tornado's generator - it is a dynamo or alternator? I believe you have converted to 12V, that will double the voltage but halve the current, you should get the same power but probably less efficient. To gain more power one would have to rewind the coils.

All I know is the generator handles a 6w H4 headlamp ok, but I don't have a picture, just a shot in the vid below. With the lithium ion battery, I don't expect any problems.

Scaly, your alternator looks either like a modern copy of the Lucas RM21, or **possibly** one of the lower-output three phase Lucas alternators like the one I bought from Al Osborn in my BSA days - it had the same colour encapsulating resin around the coils, whereas the RM21s use a green resin. Either way, that will give Kevin plenty of charging capacity. The LED H4 replacement H/L bulb I was using in my Electra-X chucked out a lot of light from only 20W or so, though as it's a modern blue-ish light I suspect that is not what you want.



Meanwhile, I have to agree with Count Johnny (yeah!) on the old-style BMW handlebr indicators, they are quite an elegant solution. Replicas are available on that auction web site, though you have to plough your way through a mass of LED items to find them.

I'm getting confused. Is this Kevin with the camping iron or Tornado with the Prince of Darkness?

I get this strange image of both trafficators flapping up and down and the bike going down the road looking like an ornithopter trying to take off.

“Meanwhile, I have to agree with Count Johnny…”


Don’t feel bad, Adrian. It happens to everyone. :-)


As an inveterate ‘changer of things’, I like the quirkiness of Scalyback’s idea – and it would certainly be an interesting feature on a ‘Steam Punk’ motorcycle.

However, if the object of the exercise is merely to indicate, one might question its utility – which probably sounds a bit rich coming from me :-) – and (never mind the current draw) I wonder about the exposed mechanism’s ability to deal with the kind of road crap that our motorcycles subject themselves to.


But - as an aforementioned inveterate ‘changer of things’- I'd love to see a neat solution that works.

Strange how this thread developed, poor Scalyback just wanted to know where he could buy trafficators, then finally the voice of reason from Count Johnny.

"As an inveterate ‘changer of things’, I like the quirkiness of Scalyback’s idea However, if the object of the exercise is merely to indicate, one might question its utility – which probably sounds a bit rich coming from me :-) – and (never mind the current draw) I wonder about the exposed mechanism’s ability to deal with the kind of road crap that our motorcycles subject themselves to."

Scalyback I for one would not presume to tell anyone what they should and shouldn't do to their bike, the current draw will not be a problem, trafficators do not as previously stated run with an armature, they are operated by an electromagnetic solenoid, by using very thin wire in the coil a large number of turns can be applied the longer and thinner the wire the lower the current draw will be and the stronger the magnetic pull will become, the current draw will be very small.

Anyone who has come across an electromagnetic door lock will verify that these doors are impossible to open when the lock is on, these locks work on 12 volts using the same principle, many thousand of turns of very thin wire, the result is they can be left on permanently without any noticeable heat and the current draw can be measured in milliamp's.

Scalyback fit and enjoy your trafficators.

Count Johnny, I was intrigued to see on the Performance Classics FB page that you went for the same ignition system on Slo Poke that I have on mine.
