Put a dim amber motion-sensor light at floor level along the path from bed to toilet and inside the bathroom. Keep that path lit all night so your parent never walks in darkness to reach a switch.
A dark trip raises danger because bathroom falls are common and increase sharply with age. The CDC counted an estimated 234,194 nonfatal bathroom injuries treated in emergency departments in 2008, with about 81% from falls, in the CDC bathroom injury report. The CDC home safety checklist treats a dark bed-to-bathroom path as a correctable fall hazard.

Why darkness hits older eyes harder
Aging eyes need far more light to see clearly at night. One review notes adults around age 75 need about triple the light of 45-year-olds for the same circadian response.
That gap means a hallway that looks dim to you may look black to your parent. In a Northern Greece study of elderly fallers, over 60% of falls happened at night getting up for the bathroom or kitchen, and about 40% said poor lighting or vision played a very important role.
What color of night light protects sleep
Choose dim amber or red-orange, not white or blue. Northwestern sleep researchers advise older adults to use a dim amber or floor-level light, avoid white-blue light, and keep it away from the sleeper, in Northwestern guidance on nighttime light.
Brightness and timing still matter. Red preserved melatonin slightly better than blue in one study, but researchers found no large difference in older adults, so red is not a sleep treatment.
Where should the light go
Light the whole route, not only the toilet. A Department of Energy senior-care trial used motion-sensor amber LED rope and recessed wall lights about 18 inches above the floor so residents could reach the bathroom without overhead lights.
Place one motion light low near the bed, one or two along the hallway baseboard, and one inside the bathroom near the floor. Face the glow toward the floor and away from pillows.
- keep sensors low so feet and thresholds stay visible
- keep light on the toilet path, with no dark gap
- use automatic or motion-on lights so no switch search is needed
What to fix along with lighting
The National Institute on Aging advises mounting grab bars at toilets and inside and outside tubs and showers, leaving a bathroom light on overnight or using an automatic night light, and placing night lights near the bed, in the National Institute on Aging fall-prevention guidance. Pair that setup with clear floors, a raised toilet seat or sturdy frame if standing is hard, and non-slip mats. Check the route at night from your parent's eye height, then dim or shield any bulb that shines in the eyes.
