Need Resource Image

Hi, can somebody tell me where can I find that glowing stuff's resource png file which is shown under the magnified icon from that dock on this image?

I was trying to find it in the ressources, but I think it is live generated during runtime.

I don't need the icon, I need the resource png which draws that glowing light UNDER the icon.
