Hi HomerChill,
Yes this is normal, please have a look on extract from our AudioFuse FAQ page :
I sometimes can see the LEDs blinking, is this normal ?
Depending of the type of use, the AudioFuse LEDs may show a blinking behavior.
This is by design and doesn't mean that your unit has a problem.
We are currently preparing a firmware that considerably reduces this effect!
I also suggest to visit the AudioFuse FAQ page, you might find some answers to general questions
