Someone did mention something about lighting a path to the bathroom but when they described it, it reminded me of those exit signs you get in case of a fire!
There are only 3 rooms upstairs, mine, mums and the bathroom, which happens to be right next to mums room, hence i was thinking along the sign lines, but i am wondering if she has problems with her eyes (booking her in to get them checked when she comes home from respite). I am grateful for all advice offered here.
Thanks for the link to the website i will have a look at it in more detail later.
