reTerminal: Control LEDs as non-admin user

Is there any way to control the LEDs as a non-admin user? Currently, I can only do the following. I’ve only been able to get it to work by doing “sudo su”:

sudo su
cd /sys/class/leds/usr_led1/
echo 0 > brightness

The following does NOT work for some reason:

cd /sys/class/leds/usr_led1/
sudo echo 0 > brightness

Is there an alternate way to control the LEDs as a non-admin user, with a Python library maybe?
