I'm guessing c_imust is not a native english speaker. I'm guessing he meant "soldering iron".
Whenever I get a chance, I'd take off "R34" and solder on a 4k7k resistor. That should reduce the light from the red powerled significantly.
Note that it is currently running at about 3.2mA, so that's the most you're going to save.
Pete, if you're redesigning the PCB, I'd appreciate it if you could make R34 and R35 (and friends) mount on bigger pads. Or maybe design a 0805 resistor R34a parallel to R34 and then mark that "do not mount". I can then remove R34 and mount a bigger resistor on the bigger pads, or on the R34a pads.
I think I'd be able do solder on a 0402 resistor like there is on there now, but I simply don't stock them because they are too small for me for normal operations....
Other option: Make a six-pad "connector". All five kathodes connect to the pads, as well as the 3.3V. Now if you remove the resistors (or leds), you can wire up external leds if you want.
