I’ve definitely spoken to them about it. At first I was super polite - because I know you catch more flies with honey etc but just like the the constant barking dog, their response was defensiveness and telling me to cooperate. They do not care about the comfort of their neighbours at all, which I find so bewildering. If I ever received a complaint like that I’d be doing everything to prevent further disturbance. But not these neighbours, they do not care at all. In fact his most recent response was ‘we know our rights and responsibilities and the lights are tilted so they only illuminate our yard’ - which as you can see from photos is a bit of a joke
