And would it likely make any difference?
The school across the road from me has new security light long that shines directly into my bedroom. Really very bright lighting, I also have a lamp post just outside the window, but that doesn't bother me at all. If they moved it just a few inches lower it wouldn't be a problem.
I'm not one for making a fuss and I used to work at the school and am scared of know the business manager. She's unlikely to say "OK we'll get it moved", although the head is more reasonable. Obviously, if I can persuade them to agree, there'll be a cost, tight school budgets etc, but isn't it reasonable to expect a school to consider their neighbours?
Would you bother trying to get it moved? Do I even have any right to expect that they might?
