How To Disable Green LEDs On a Raspberry Pi Zero

Published December 29th, 2020 by Emily

To temporarily disable the lights, run the following two commands:

echo none | sudo tee /sys/class/leds/led0/trigger
echo 1 | sudo tee /sys/class/leds/led0/brightness

To permanently disable the lights, edit the boot config file using the following command:

sudo nano /boot/config.txt

Once in the file, add the following lines to the bottom:

# Disable the ACT LED on the Pi Zero
dtparam=act_led_trigger=none
dtparam=act_led_activelow=on

Exit the nano text editor using ctrl+X and enter Y to save. Then reboot the Pi using the following command.

sudo reboot

I got this code from here, but the formatting on the website was a little messed up so I reposted here.
