Would you report a red light jumper?

I doubt anyone would report it, but why did you not slow down and stop when they changed to amber? If it turned to red as you were passing through then you would have had enough time to stop safely.

Honestly, yes I would have had time to stop but I just had a complete brain fart. I was changing lane to get into the right turn lane as I was turning right at the lights and I just sort of didn't pay enough attention to the lights even though I clearly saw it change to amber. The traffic on the other side was still stationary when I went through their light only went green after I had gone through and was in the process of turning. I won't be doing it again for sure.

Some jobsworth might if they're having a bad day, but realistically, nothing will likely come of it. Just be aware that some lights have very tight timings, particularly at night, where two conflicting directions can both show amber at the same time, so even if you have to go hard on the old anchors, it's probably best to do so unless you're gonna get rear ended. I wouldn't advise doing it if you were being closely followed by a HGV for example, they can stop very quickly, but not as quick as a car, sudden braking could mean as much 46 tonnes of lorry rear ending you... Not a pretty sight.
