download Light Flow - LED&Notifications v3.12.6

Light Flow allows you to take control of your notification LED colors and makes them successively flash one color after another.

This program will allow you to control the notification color for the over 600 applications and system events such as:
* Missed calls
* Voice mail
* Calendar reminders
* gmail
* email
* SMS messages
* MMS messages
* Low battery
* No signal
* Google talk
* Facebook
* Twitter
...and many many more

It allows the colors to flash in succession, so if you have a new SMS and a missed call it can alternate between the two colors. You can also set which notification type has the highest priority and let it flash in just that one color.

It'll even push notifications out to your pebble smart watch and the DashClock lock screen extension.
