It does seem to work a little bit, make sure you (obviously) have root and have enabled accessibility and in the settings enable "Direct mode." I haven't had much time to play with it too much but it does seem to work, just play around in the settings and configurations and see what you can find out and post what ya find.
I use it on mine. Basically you can have choice of 3 colors. I just make it keep the light constantly on when I have a notification. The rezounds notification led is way too easy to miss the way it is.
