A good thought but no. LED's are usually of constant brightness and the tails in this 2 second exposure should be of the same colour and brightness. But here the bright white lights are of a different colour than the tails which also seem to vary in colour. In addition the bright white lights are more widely spaced than the tails, so again don't fit. It's a bit of a mystery, isn't it. And no there aren't any clues from my site yet.
Here is another related photo. I will give progressive clues with more guesses.

Hmmmm... Too hard My son gave me a bubble generator for Xmas. The unusual reflections are due to a combinaton of the oblique lighting, long exposure and flash as well. The last pic is a nice little scene in a bubble of me and my son with some trees in a bubble. Note the loss of reflection at the top as the film thins (to ?less then 1 wavelength of light thick)

Why cant you see camera reflection? i bet you could sell some of your photos..
The camera in the bottom photo did not have light behind it to form a silhouette. I did try sending some of my best photos off to ShutterStock. All 10 were rejected. Mostly they look for a pretty girl in a lab coat looking at a flask of blue liquid to represent science. Hundreds of these. Go figure. Even Scientific American had one of those cheesy shots.

Yes it was too easy. I should have only showed one pixel. It shows the fluorescence of scorpions to violet/ultraviolet in a 3 second exposure with the Blu-ray pointer. I found this one in our kitchen.
Not easy to take though. Consider. One hand is perfectly still holding a live scorpion and the other triggers the camera AND moves the laser - in complete darkness.

Just one of those "I'll take it straight back to its mother" type scorpions. Actually that is the only size we see here so I guess full grown or maybe that's as big as will fit under the door. ...is that someone knocking?....
