Oh, wow! Those circuits are a bad example of how to use LEDs properly. That single high-power LED should work on 4.5V with that orange-white-gold (3.1 ohm) resistor. Is that the one that it was originally using? It looks to be undersized, but it would be about the right value. That resistor is going to get hot, though, so don't put it up against anything important.
If you can't come up with some different resistors and/or rewire the LEDs in the wings, those aren't really going to work right. That one big brown-green-gold (1.5 ohm) resistor only just sort of works with 4 parallel strings of 6 parallel LEDs running on 4.5V. That's a very poor way to drive LEDs.
