Notification lights are something most users don’t think about. As long as the lights go off when they’re supposed to, few pay much attention. In most cases, to modify notification light settings, one needs at least root. Now, there is an application that lets you alter notification settings without root.
XDA Forum Member MOST2K2, who also brought social networking app SNOView, has released an application called LEDBlinker. The point of the application is to give users a variety of notification light options, without requiring root. Some of the features include:
* Let your LED show your missed calls and sms
* Battery status (LED lights up for low battery)
* Alternative On-Screen-LED
* Autostart function after device reboot
Of course, the capabilities of the application is limited to your hardware. If you don’t have multi-color LED notification lights, you obviously won’t be able to take advantage of that. If you don’t have notification LEDs at all, the app can help you configure your screen to flash when you have notifications.
