The original LightShapes library: LightShapes.sh3f
You can read more about it here (heading "More lights capabilities") and here (halfway down the page).

I think I spoke too soon. I can't seem to download the file. I click on the link but nothing happens. By contrast I went looking for other links for it and found a few at a page called Sourceforge called 'Logos Lightshape' and 'Neon Light shape' and those downloaded fine. I saw the confirmation messages stating they were added to the libraries, but not for the original Lightshapes library.
Here’s a pic of all of my light options currently under the search word ‘light’. Unless that library was incorporated without letting me know, but that would be a 1st so far.

Does that link work for you? Do you have another I might try?
