Moto X Play notifications
apps like IFTTT are used for automating work by creating a recipe or using the one's already available, it won't help you enable your LED notification light. 
Someone from Motorola Customer Care stated-
"Unfortunately, you can't enable the notification light of your Moto X play, this feature is not available anymore, we have replaced the LED for Active display, It will show notifications as well, the LED that we have included is just for emergency It just light up when your device is full of charge or when It needs charge."

The gist comes out, that you must root your device in order to use the apps available on the Play Store to enable the LED notifications.
