If you click the script and all the lights are OFF, the script will turn them all ON.

What's new in V2.0

-I received a mail from a user with an attached file containing a collection of Corona lights,
Where the script turned everything OFF as it should, but for some reason the script failed to turn them ON again,
After inspecting the script that problem/bug was fixed.
	

The script can be used freely for personal and commercial projects.
