could any offer us advice, as its been shining into bedrooms until 2 in the morning and affecting us severely? the lights purposely angled towards our bedrooms.
I couldn't make much out from the picture...are those lights directly underneath your neighbours house and his windows or are they directly up against your wall and underneath your windows?
Sometimes local councils have a neighbourhood liaison officer who may be able to help mediate with neighbour disputes. Your local council also may be able to offer you further advice on what may constitute light or noise pollution?
Failing that, it may be possible that your neighbour is trying to intentionally disturb or offend you- in which case I would buy blackout blinds and blackout curtains and not let him win!
Best of luck.
