Lights have gone wrong again as they did a few days ago.

No green phase if you are coming along Cranston Road. Drivers are taking a chance and are crossing the South Circular when the Brockley Rise direction has a green light, but being careful of turning traffic.

I have reported it on the Transport for London website, but if it has cleared itself then please let me or TFL know.

Working OK now.
And a nice "thank-you" phone call from TFL for reporting the problem to them.

Aha that would explain all the car horns I could hear honking when I was in my back garden. I just thought the SE London drivers were being particularly grumpy that day....

Sometimes it may have something to do with the traffic sensor. If cars do not move and trigger the sensor, the machine thinks there are no vehicles in Cranston Road and does not give it a green phase. I am not sure how this happens.

Lights were broken again at around 6.15 this morning. Looked like the sensor atop the pole pointing down Cranston Rd was pointing nowhere near traffic - I presume it's a microwave vehicle detector as there don't appear to be any inductive loops in the road. Not sure if they change to timer-activated later in the morning as they were fine around 8.45am.

On Saturday, it took two complete phases to get a green light to exit Cranston Road. Is this normal?

The pedestrian green light on Stanstead Road only operates when Cranston Road has a green light. I am guessing that the motion sensor was not working, but someone pressed the pedestrian button.
