An indicating device fastenable using a fastening band includes a housing, a light source mount having a light source module secured at a front end of the housing; a rear cover fitted at a rear end of the housing; a reset spring secured in the housing using a spindle screw and a nut; a metallic movable shaft mount, the reset spring having an outer end positioned at a lower end of the movable shaft mount; an electrically conductive spring secured at a central portion at the other end of the movable shaft mount, and a rotary shaft mount having a lower end disposed in an annular groove at an outer side of the movable shaft mount. The rotary shaft mount is internally provided with a battery chamber adapted to receive two batteries, one end of the batteries pressing against the electrically conductive spring with the other end resting against a positive conductive plate of the light source module entering from a through hole in front. The rotary shaft mount has a fastening band passing through a through hole of the housing to the outer side. The fastening band has a metallic fastening plate at a front end thereof. The fastening band is wound around an object to be secured with the fastening plate inserted via a conductive plate groove to be engaged in a reduced portion of a fastening slot of the housing such that the fastening plate is in contact with the metallic movable shaft mount and the conductive plate in the conductive plate groove of the housing, thereby electrically connecting the light source module to achieve illumination or indicating a target object.
