I would guess that it would be the Super Bright pink LED SKU: A-4732 from Tayda, whatever LED you use make sure it is Super Bright with very high MCD rating.
You can increase the brightness of the LED by using a lower value dropping resistors R4 and R6, you can lower the resistor as low as 510 ohms and still be within the LED's specs. I think I often use 820 ohms for my LED resistors on my builds.
The resistance will vary with the LED choice also, the pedal can take 12v and the pink LED has a voltage drop of 3.2v so you have 8.8v over the resistor, if you use a 820 ohm resistor you have a current of 10.7mA going through the LED
12v-3.2v= 8.8v, so - 8.8v / 820R = 10.7mA (0.0107 Amps)
If you want to run max current which is 20mA you use 8.2 Volts / 0.020 Amps = 440 ohms.
I would never use less then 510 ohm and I prefer to go to about 10mA to 15mA in my LED's
You can also put reflective tape inside the box to reflect the LED light better of the walls but I would not go that far myself, I got some spare copper tape I use in my guitars to limit interference so I might try it one day though.
