 David,
I just want to be sure...my email says 470R for the resistor.  I am assuming this is 470 Ohms, I guess like a 1/4 Watt resistor (dang, I have not even said that phrase in 40 years!  I guess what you mean is super small size wise).  And like you said, a little extra if too bright.

470R ought to be safe.  All the panel LEDs use 470R.  Beyond that, increase
resistance to make it dimmer.

I know 5V ones exist because I've bought some.  Not widely available
though.  Ah!  This outfit has 3mm diffused yellow 12V ones at $1.40 for
five.  Comes to $5.35 with shipping.

REmember though you may need additional resistance to tone it down.

Yrs,
