Nexus 5 Led doesn't work (PA 5.0-ALPHA2) topic

Hi everyone!
Today I've switched from CM11 to PA, and really like it.
But I've noticed, that the notification LED doesn't to anything (neither charging, nor any notifications).
Pulse Notification Light is turned ON, but whether its on and off the result is the same.
I've downloaded Light Flow to test the LED, but its still dark.
Can you help me out?
Thanks in advance:
Aaron
