Passing switch conversion

[Roger]

If you find a Haynes book, standard UK 1100 wiring is straightforward. But..... in my book, there is a mistake where the flasher is marked as a second clutch switch!

Or while in anger, grasping clutch, horn and PTF button with my left hand, while braking hard for that knucklehead running a stop sign, etc...

On occasion I think of wiring the high beams to a strobing flasher unit and connecting it to my FIAMMs. Honking the horn would flash them. And wired so that flashing the high beams didn't honk the horn. That's as far as I get.
