Orange Solid = Phone Charging but not full
Orange Blink = Overheating and I think notification for text and voicemail
Red Solid = Something is attempting to charging but not charging
Red Blink = Low battery
Greenish On = Phone is done charging
Green Blink = Radio Check
Blue = Obviously bluetooth

I think that pretty much covers the LED indicators.

If you need more you can try out nueLED and see if in the documentation it mentions others..as it is a tool that lets you control the LED indicators.
