a safety cover for use on a handrail , grab bar or peripheral edge of a fixture or object at a darkened location . the cover features a longitudinally split tubular member of resiliently flexible material and an illumination source carried thereby that is operable to provide illumination of the darkened location . the tubular member has a circumferential resiliency that biases two free edges of the tubular member toward one another from to automatically close up the longitudinal split , whereby the tubular member frictionally grips the rail , bar or peripheral edge over which it is placed . an illuminating floor mat or toilet lid cover features at least one longitudinally - shaped illumination member running along at least one peripheral edge of the mat or cover with one or more light - emitting areas of said longitudinally - shaped illumination member in a visually detectable position left unconcealed by the mat or cover .
