North arm of the A6 clophill roundabout, same side as the flying horse pub

Pushing the button on the toucan crossing here causes a red light on the button to appear, but this cancels after a few moments and does not change the traffic signals. The button has to be pushed again.

This happened to me every day last week without fail.

You only realise it's not working after you've waited for ages and then realise the red circle light around the push button is not lit.

Additionally, on several recent occasions we have found that buttons sometimes do not work at all, and we have to use the other button. This usually happens on the other side of the road.

I have also noticed on other occasions that the beeping sound doesn't work, although this does T happen very often, or perhaps was fixed.

I do feel unsure about the safety of these lights given the apparent hardware/software issues in something so safety critical.
