You cannot achieve flicker free lighting by converting to electronic ignition. The lighting and the ignition are two separate circuits.
Often on a standard six pole stator, four coils are dedicated to lighting, one to ignition (the low tension coil) and the final coil position is occupied by the electronic ignition trigger (or points on an only stator). When the headlight is on, it is powered directly from the coils, and therefore it is affected by engine speed.
What you need is a battery in series with your four lighting coils. OK, you have a battery, but I imagine it is there to power the horn, side light and brake light. You can test this by disconnecting the battery and finding out what no longer works.
So the question is, how can the battery be utilised to to stabilise the voltage, regardless of engine revs. There are going to be several different answers to this, but perhaps a sensible question would be, what is wrong with flickering lights at tickover?
