Re those mini LEDs...
Go by trial and error, and start with 3000 Ohms...

I have various resistors from 400 - 2000 Ohms,
and connect them in series, with a 16v DC power source,
then remove one at a time, until I feel I have found a good value.

However, maybe it's better to try at the decoder outlet directly,
as some LEDs apparently are more sensitive to the current coming from a decoder,
than to straight DC.

Guess why I know.

And, the same LED from a different supplier,
may burn out at another value.
