Dim or Dimmer
I tried a translucent plastic strip over the LEDs to hit a midway point between paper and nothing. I don't think it diffuses the light as much as I had hoped. Hum...
I got a LM2951 voltage regulator that will supply a constant 3.3V @ 100mA, I will try that out instead. I won't need any resistors, because the 100mA divided by 8 LEDs would be 12.5mA per LED, so they will be dimmer to begin with. Also the LEDs will be the same brightness despite the fluxuations in the battery pack. I guess if 100mA is not enough, I can run the signal through a transistor, and be able to pick just the right brightness. I could even make it adjustable!
