You already know the route. It runs from the bed to the bathroom, and some nights it runs through a hallway you walk without looking. Your parent cannot walk it without looking. If the switch sits on the far side of the doorway, or a lamp cord crosses the path, the route becomes a guess, and guessing in the dark is how small trips turn into bad ones.

This guide is about sizing the lighting to that route in your house. It does not replace an eye exam or a visit to the doctor, and it is not an electrical job. It is a list of what to measure, what to ask, and who owns each piece.
Walk the route at the hour it actually happens
Pick the hour your parent really gets up, not the hour you wish they slept. Turn off every light, stand where the bed is, and walk to the bathroom at the pace your parent walks. Count the steps. Note every doorway, rug edge, step up, and cord. Write them down in order, the way you would describe the house to someone who has never been in it.
Measure where the hand lands
Have your parent sit in the bed, or in the chair they use at night, the way they would sit to start the night. Ask them to reach out without standing. Mark where the hand naturally falls. Then measure from the floor to that spot, and from that spot to the nearest existing switch. If the switch is across the room, or behind a door that swings into the path, the switch is in the wrong place for this body and this bed.
Repeat the check at the bathroom door. If the light is on the far wall and the door opens toward the person, the switch has to be reachable before the door is pushed, not after.
Choose the light for the job
Three kinds of light solve this problem, and each does different work.
A bedside lamp with a base switch or touch control gives your parent light without standing. Check the base weight so it does not tip when touched, the cord length so it does not reach the floor path, and whether the switch works from the bed. Test the lamp with the bulb you plan to use, not the one in the box.
A motion-activated night light along the route lights the floor, not the whole room. Check where the plug sits and whether a bed, dresser, or cord would block it. Check that it does not shine straight into the eyes of someone lying in bed.
A new or moved wall switch changes the wiring. Ask a licensed electrician to quote the move, to confirm where the switch can safely go, and to tell you what the wall box needs. Do not attempt this yourself unless you already know how to do it.
Decide who owns each light
Write one name next to each item: who replaces bulbs, who checks that the night lights still turn on, who moves the lamp back when a cleaner shifts it, who calls the electrician if a switch goes dead. A light that nobody owns is the one that quietly stops working, and nobody notices until the night it matters.
Test it in the dark
Turn off everything and walk the route again, at the same hour, with your parent if they are able. Stop at each switch and check that you can find it with the hand that will reach it. Check that no light glares into the bed. Check that the route is lit before the first step, not after. If anything surprises you, write it down and fix that one item before you move on.
When it works, nobody has to stand in the hallway at 3am wondering whether the light is on. That is the whole goal. Start with the route you wrote down, and keep the list where the next person can read it too.
