Tiger Cub Upgrades

Hi All
My Dad has just bought his boyhood first bike, a late 50s cub (can’t remember exact year).
Points sticking up out of the crankcase I believe.
He wants to do a few things just to improve his enjoyment of it.
First is a 12 volt conversion which I think we are ok with, second is an electronic ignition conversion (prefer a conversion with minimal mods) and third is to fit some indicators.
Any advice on the above is much appreciated.
Thanks in advance.
