Correct.
Pic shows the context.

Next is Mystery photo 54. This is harder and I may need to give a clue.

Seems like you need a clue.
If you could spectroscopically analyse that light you should see lines characteristic of sodium and mercury.

Here is a wider view.

More hints. Where else do you see red and green lights? I can't post again until someone else has a go.

I'm guessing a long-exposure shot of two neon tubes, mercury vapor lamps, and sodium lamps. Maybe they're on a carnival ride of some sort, or somehow moving, or maybe you're shaking he camera. cheesey

It's street lights and traffic lights at night. A time exposure from a moving car, or more likely a bike, knowing TDU smile

This thread is a sleeper that is about to rise like a Phoenix from the ....whatever.

Yep the last one was traffic lights and sodium street lights from a camera on the dashboard. Well I was bored...

Photo shows the full shot. Kinda interesting.

Next photo Mystery 56. What do you expect, I am a true blue Aussie. (hint)

Next photo looks like a grinding wheel showing sparks of metal whizzing by. Very brief exposure. If the color is anything like that in real life it's probably titanium.

Not grinding sparks.

Type in Aussie and the date of the post into Google. (a hint about the hint)

Photo shows Tungsten grinding sparks.

It must be some kind of fireworks then, but the background looks like it's going by real fast.

It was fire works for Australia day.

Photo 1 shows detail of a similar firework.
Photo 2 shows the full pic. The horizontal displacement is due to camera shake. I did a few manual shutter shots rather than my usual IR remote trigger. It was only 1/30 sec and the displacement is down not across.
Photo 3 Shows the wind effect.

Photo 4 Mystery photo 57
