Yes, good eye!

My suspicion is that the ghost images are from reflections off the glass on your mirror. The entire image is getting ghosted (not just your LED), but the ghosts are weak (~5% of the normal reflection), so you can only see it for the bright green light on the black background.

So why is there a ghost to the left and right of the image? Remember, your mirror consists of a clear slab of glass with a smooth metal film on the back. The "regular" image you see comes from the light that goes through the top glass interface (air-to-glass), reflects off the metal, goes back through the glass interface (gladglass-to-air), and gets to your eye. The ghosts come from extraneous reflections at those glass/air interfaces (5%, as I mentioned before). The first ghost comes from that first interface (appearing to the one side of the regular image). The second ghost comes from the second interface, sent back to the metal (appearing to the other side of the regular image). There will actually be more reflections, 3rd and 4th etc., getting progressively (and quickly) weaker.

I don't think the bevel is relevant for the ghosts around your LED. I'll say it again.: Good eye! And good for you for wondering about it.
