It is quite weird why Motorola didn't use the notification Led. The only way to activate this feature is bu using a custom ROM such as Cyanogen Mod(This is what I am currently using). But this step includes unlocking the bootloader, flashing a custom recovery and installing Cyanogen. This is a dangerous process and should not be done by amateurs.
