All of this is straight forward if you have worked with electronics. I put the batteries in series, soldered in the resistor, then the switch, then the LED.

I want to point out that you have to have an entry and exit for the switch and LEDs and arrange everything before you solder. May seem obvious, but it will save you time from having to go back and cut and resolder everything. Trust me, I know :(.

oops, I had it setup with the switch before the resistor, but it should work either way.
