LED Control

The front bar and standby LEDs are driven by the ICC (Internal Controller Chip) - a preset driver is built into the kernel via drivers/ps5/led/ (merged in ps5-linux-patches commit 6479385).

Sysfs interface

/sys/class/leds/ps5:<preset>:indicator/brightness

Write 1 to activate a preset:

echo 1 | sudo tee /sys/class/leds/ps5:purple:indicator/brightness

Turn the LED off:

echo 1 | sudo tee /sys/class/leds/ps5:off:indicator/brightness

List available presets:

ls /sys/class/leds/ | grep ps5

Hardware notes

The LED has two independently addressable zones:

• Zone A - main front light bar (blue, white, orange channels)
• Zone B - secondary LED near the power button, used for standby breathe animations. Not user-visible during normal desktop use.

Channels overlap in perceived color - blue and white both wash out orange at high brightness, so pink/purple presets keep orange near max and the other channel(s) low.

Reading the boot-status LED

This is separate from the presets above - see Booting Linux for what the stock orange/white LED states mean during the loader handoff.
