I have created a [batch file](https://www.dropbox.com/s/gul27bzlxgss931/Reconfigure_Lighthouses.bat?dl=0) that will go through this process (except restarting your PC).

It is untested (I don’t have PiTool or my headset) so I would appreciate if @Sjef and/or some other code monkeys would take a look at it.

**EDIT:** It is extremely ugly but heavily commented. Who knew that commenting in a batch file would look that bad.

**EDIT** Here are the contents of the batch file (in case the Dropbox link gets broken at some point). To make your own batch file just copy the contents into a text file and change the extension from “.txt” to “.bat”.
