Flood lights

Blackout blinds would be as claustrophobic as the blanket over the curtain rail.
I’ve only seen this neighbour once, she does keep very odd hours so maybe works shifts, but I will tell her when I see her again.

To be honest if you sleep with your curtains open, NotTooOld which is of course your choice, you ll have to accept that there will be lights from others shining into your bedroom I have a street light straight outside my bedroom and live where there is nighttime traffic so blackout curtains are definitely a boon for me as neither the streetlight or the traffic could be ‘talked to’
Have you tried blackouts Watermelon ?

Fortunately our security light doesn’t disturb anybody else,
And in fact we only had it fitted for ourselves, the light is useful for getting out the door key and getting into the house.It probably gives visitors a fright though, as they approach the door, the light is blinding.
At our last house, we did have a word with a neighbour about their light, they didn’t realise it was shining into our window.Most neighbours are reasonable if approached in the right way.

Years ago we had lights put on the corners of our house......we didn’t realise the bats would trigger them so very regularly!

tanith - you are right of course. I've actually been meaning to do that for ages!

I would like to have a security light, one that would come on when I go out of the back door or come in from the garage, but I know that if I did all the blasted cats in the neighbourhood would be forever triggering it, annoying the neighbours.

Ask the neighbour nicely to adjust the angle of the sensor there is no need for animosity. If they don't know their light is shining into your bedroom then you need to enlighten them.

We have the same problem and it is so annoying. We like to sleep with our curtains open, so blackouts won't work for us. I don't know why people feel the need to have floodlights on all night. Another neighbour has one which comes on only if there is an intruder but that apparently includes the odd cat or dog that wanders past and then the light comes on and shines in on to our bed.

Complain to her - very nicely! Our neighbour complained about our security lights on the drive so we changed the angle of the sensor - everyone is happy.

Could you get some blackout curtains or blinds? They're very good for blocking out lights.
