The cheapest fall-prevention measure in the house is lighting the route to the bathroom.
Verdict
Use motion sensor lights along the route to the bathroom, and put a small always-on light in the bathroom itself. Motion sensors light the path exactly when someone gets up and stay dark otherwise, which preserves sleep. An always-on light removes the one failure mode that matters: a sensor that does not trigger because someone moved slowly or approached from the wrong angle.
Night-time falls are one of the most preventable categories of injury in older adults, and the circumstances repeat: getting up in the dark, blood pressure dropping on standing, eyes that adapt to darkness far more slowly than they used to, and an unlit route with a rug or a threshold in it.
Lighting the route is close to free, requires no conversation about capability and no equipment anyone resents, which makes it one of the easiest safety measures a family can put in place.

You are lighting a bedroom-to-bathroom route. Place one low on the wall near the bed, one in the hallway, one at any doorway or step, and one just inside the bathroom. Low, warm light is what you want: bright white light at 3am wakes people fully and causes glare, which is its own hazard for ageing eyes. Test the sensor by walking the route slowly, the way someone actually walks at night.

The lighting problem is not the route but the reading, in which case a lit magnifier or better task lighting is the answer rather than a night light. Low vision and poor lighting are separate problems that get confused: if your parent struggles to read, see the reading glasses and magnifier comparison, and get their vision checked, since cataracts and macular degeneration are common, treatable and a genuine fall risk in themselves.

Also remove or tape down rugs along the route, clear cables and clutter, make sure there is a lamp reachable from the bed, and consider a grab bar beside the toilet. Ask their doctor to review medication, since sedatives, blood pressure medicines and some antidepressants increase fall risk, and to check for postural blood pressure drops. Annual eye tests matter: uncorrected vision and old spectacle prescriptions are a documented contributor to falls.
Enough that no part of the route is dark: typically one near the bed, one in the hall, one at any step or doorway and one in the bathroom. It is cheaper to over-provide than to leave a dark corner where the turn happens.
Mostly, and the failure mode to test for is slow movement, which some sensors do not register well, and approach angles outside the sensor's cone. Walk the route slowly at night before relying on it. Pairing motion lights along the route with one always-on light in the bathroom covers the gap.
Warm, dim light. Bright white or blue-toned light at night causes glare, wakes people more fully and makes it harder for ageing eyes to adjust. The aim is enough light to see the floor and the doorway, not enough to read by.
Clearing the route of rugs and cables, a reachable bedside lamp, a grab bar by the toilet, a commode if the walk itself is unsafe, and a medication review with their doctor. Sedatives and blood pressure medicines are common contributors, as are uncorrected vision problems.
