The green LED does look very bright. This is probably because the manufacturer used a green LED that’s different from our original spec. The current flowing through the LED is about (5-2)/1K = 3mA, which is pretty normal. But if the brightness bothers you, you can remove the green LED or the 1K resistor next to the LED.
