Assuming you are the registered keeper (that is, it's your name on the V5) you need only wait 14 days from the offence to find out: you'll be sent a request to name the driver under S172.

In fact crossing on amber is also an offence, but it's likely that the camera is set to trigger a very short time after turning red.

I rather shame facedly admit to having been flashed by a traffic light camera, I say shame facedly as it is dangerous driving. I received no penalty, so clearly there was no film in, or the digital bits were wonky. You will find out soon ...

I would be surprised if you got a fine, you was over and past the line or radar but as I recall it would be too dangerous too stop on amber light if you are going through as it changes

I've seen traffic light / junction cameras being triggered and the flash is VERY bright, even on a sunny day. If it flashed you, you will have seen it in your mirrors.
