You can now get updated whenever there are notifications with the help of this app!  The Flash Alerts on Call and SMS app notifies you by making blink flashes on your mobile phone to alert you whenever you receive a message or missed a call. You can still use this tool even if your device is in vibrate or silent mode. This can also help if you are in a dark environment and you do not want your screen screaming with brightness.

You are allowed to customize the blinking time and just set the flash alert whenever you need to use it.
