An elderly lady that I do odd jobs for has been recommended to have a
safety gate fitted at the top of her stairs (she's in a first floor
flat). Her bedroom door is immediately opposite the top of the stairs
and there's a concern that she might get up in the night and walk out
the bedroom door and forget to turn right or left!

Would a PIR attached to the landing light do the trick, so she wouldn't
be in the dark - or is it more a question of confusion and/or poor vision?
