To clarify, the LED and CAP are parallel, and the both are series with 
the diode. The LED anode and diode cathode are connected together.

There were  half a dozen suggestions, I experimented with the ones where 
I had stock of the pieces. For the moment (several days) it's still 
working. Should get thunderstorms this afternoon,  maybe (hope not) a 
near lightning strick might change that.

I'll save all the suggestions, and if need be, pursue other ideas as 
need be. Thanks again. :)
