Hmm, you may have a point, I don't like those "IF one goes out they all go out" old time Christmas lights, don't want the leds to all fry if one goes out, so maybe the resistor would be a good saftey measure for that. SO far I haven't needed it, YET.
As for the led colors. I don't know what he has for the light string, but mine were colored plastic and most likely all the same led inside. Maybe all whites shining though red or green or blue plastic. Really just a little glowing light inside plastic is all they were, but all one piece, not like an led with a plastic cover over it.
I do have real leds that all are clear when off, then some are UV, red, ect.. when lit.
Kinda hard to tell whats what if they get mixed unless I put power to them. Definantly not the same thing as the Christmas lights leds I had but more like whats being mentioned here probably.
.
nothing to lose
Spelin and tpying are my strong points, not electronics.
