Seems to be an alternator thing.

I have had  LED instrument\generator(red) bulbs since 2009.  

 Works as intended like original incandescent lamp. Lights up at low idle etc.

My understanding is that an LED is fine for a dynamo, but for an alternator the current generated by the warning light is what gets the field coils energised, and LEDs pull so little current that the field coils will not energise, and so no generation takes place.
