Another danger arises from buses turning right onto Peckham Rye from the Nunhead side. They block your view of the oncoming traffic so you don't know whether the cars have stopped at the light or not. By the time the bus has turned and you can see properly, the traffic starts to advance from the side and you're trapped in the middle of the junction. Unfortunately, a filter light alone won't stop cars jumping the lights, it would probably take a camera to do that.
