The SureStep Cane Tip installs easily on most 7/8″ standard walking canes, making walking at night or in low light conditions easier and safer for the elderly and disabled. Installation is simple and requires no tools, and SureStep uses standard AAA batteries; an automatic light sensor triggers at 10 lux (or twilight conditions), and automatically powers off when not in use. Perfect for walking at night, getting safely to bed, and more.
