I made an app with Tasker App Factory that does what the original post explains in a video (http://m.androidauthority.com/moto-x...cation-331710/), for those that don't have/want Tasker.
This is the first time I've shared anything that I've made in Tasker, and I can't say why it has some of the permissions it does, honestly. If anyone cna elaborate on why it does has those default permissions, that'd be great.
DISCLAIMER: As I stated above, this is my first app. I tested it on my Verizon Moto Maker edition Moto X that is rooted on 4.4. I take no responsibility for what happens to your phone or anything you do with this app. It worked fine for me, but I make no promises it will work for you.

- Latest one adds in a few more options for how the light is displayed, and a brightness setting.

Install, run, and accept the root request (root is needed for the shell command, just as it is in the Tasker profile). It will also run the command when you boot, and starts working a few seconds after the phone turns on.
Note: If you decide you don't like it and uninstall the app, you will probably need to reboot after uninstalling to disable the LED.
Hopefully someone finds this useful. I personally don't care for it, but I like making stuff in Tasker and thought I'd give it a shot.
