There's no offence for running an amber light... At most you might get pulled by a copper (On the off chance that there's actually one driving behind you) who'll use it as an excuse for a routine stop to check if you can legally drive and whatnot.
As for red light cameras, most of the time they look exactly like speed cameras because they also generally act as speed cameras (deters people from speeding up on amber and jumping the red light). I don't mean the smaller SPECS cameras either, I'm talking about the big chunky, can't miss the f*ckers cameras. You might come across the odd red light camera that only monitors red light jumpers, in which case, they'll look like your normal, big, f*ck off speed cameras, but they'll likely be grey rather than yellow.
