I've found some interesting behavior in Chatter, and was wondering if others can confirm it. If the LED is lit for a different reason (example: you have new voicemail, which for the sake of argument is configured to light the LED steady green) and then new email comes in, Chatter changes the LED appropriately (to red, let's say) if you have that notification set. However, once you read the email, Chatter turns off the LED. Shouldn't it go back to the state it was in before (green)?
