Abstract
A belt includes one or more tension members extending along a length of the belt, a jacket at least partially enclosing the plurality of tension members, and one or more layers of one or more of a fluorescent, absorbing, or reflecting material located in the belt such that when subjected to a light source, an indication of fluorescence or absorbance or reflection of the one or more layers of fluorescent or absorbent or reflective materials is indicative of a wear condition of the belt.
