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.
