Help LED indicator stops flashing

[Gobstopper]

The Inc is my first smartphone so I don't know anything about how the LED indicators work. When I get emails and texts, I get the green LED indicator that flashes. Is the LED supposed to keep flashing until you clear the email/text from your notifications panel? I ask because I got an email last night and I didn't check it until I woke up this morning and the LED indicator wasn't flashing anymore. If this is intentional, what's the purpose of having the LED flash for only a limited amount of time?

It's intentional, it saves the battery. Mine flashes for about 5-6 minutes.
