So what did I do? Two things: (1) replaced the ignition coils with new. (2) checked and cleaned a few nearby earthing points. First was a fine black wire leading to an earth connection adjacent to the ignition coils - on the alu frame that the coils fix to. Second the frame that the coils fit into had some corrosion on the metal surfaces - so I cleaned these. Thirdly the earth strap that links the chassis to the bonnet catch on LH side (i.e. near the ignition coil) had frayed so I tightened the chassis connection, cleaned the strap and added a new connecting strap.
Hopefully this has properly solved the intermittent battery light!

Now I might well be talking out of my arse, as I'm no electrician......
...... but I am led to believe that the teltale light wouldn't work CORRECTLY with an LED 'bulb'.
My understanding is that when you first switch on the ignition, there is (may be?) no light iluminated as it requires current to flow the 'other way' - but once the engine is running, it will behave as normal.... but I could be completely wrong

Just two LED's in parallel with one reversed will provide a light whichever the polarity. You can get them made like that but I've only seen big ones that wouldn't fit without a lot of mucking about with instrument cluster. Direction Indicator would need one too if you were converting to LED's.
