HTC Nexus One

My LED indicator light or battery indicator light doesn't blink when i have a new email or voicemail or text message and wanted to know if its just my phone or if the nexus one just doesn't blink when you get a message or something cause the only thing that lights up is the trackball and screen. If anyone can help me that would be great i tried downloading chompsms so i could change the color of the LED blink but it wont do anything even when I do a test notification on it. Don't want to have to return it if I got a dud or go back to the HD2.

Thanks Again.
