Yeah, I understand all of that. I will be wiring the LED running headlight in sets of 4 LEDs with a 180ohm resistor for each set.
One resistor per LED will will end up wasting a good deal of power relative to the LEDs themselves. I didn't realize that when I made the brake light array, so I will be replacing it with two sets of four 14 lumen LEDs.

There's not much voltage drift in the power supplied by the DC-DC converter, so I don't have to make my arrays for as wide of a voltage as I would to power them from a battery.
