For those of us who prefer to keep their device on silent mode and do not have a dedicated notification LED, it can be a nuisance to wake up the device in order to check for any new notifications. While there are already ways to turn your device's hardware keys or screen itself into a makeshift notification LED, such as BLN and NoLED, these are sometimes incompatible with certain devices and/or ROMs and kernels. ButtonLED from XDA Senior Member GermainZ might just be a viable alternative to these existing solutions which should work on all rooted devices, as long as they have a flashlight and proximity sensor. Unfortunately though the application will not work on devices running a Jelly Bean based ROM, yet.

The app was created using Tasker on an MDPI device, so users with a different screen size may notice some aesthetic irregularities but let's be honest, an app like this is all about functionality and not aesthetics. You do not need Tasker to run the app itself, though. It's a standalone application and not a profile. Some of the current features include:

• Status bar notification & missed call/SMS support.
• Turning the button backlight on for a set time and off for a set time.
• Notification exceptions
• Logging

If you'd like to know more about ButtonLED and try it out for yourself, you can find the original application thread here.
