Excuse my ignorance on the following subject as I have no PS3 and thus I am unfamiliar with the controller lights.

A couple of days back after getting a bit too into playing the Black River on GHMetallica, I noticed that the other 3 LEDs on my GH drums would flash slowly, as in slower than when the controller is trying to connect to the dongle. I dunno if either my drum batteries are dieing, or if I did play the drums a bit too hard to upset it. Though I am leaning towards the former possible situation.

EDIT: With some help narrowing it down with my YIM friends, it is indeed a low battery indicator. Close topic as needed
