Systems and methods for interactive objects including illuminated surfaces are provided. An interactive object includes a flexible substrate comprising a soft material that is non-transmissive to light. The interactive object includes a plurality of holes extending from an inside surface of the flexible substrate to an outside surface of the flexible substrate to form a light-transmissive pattern at one or more locations of the flexible substrate. An illuminated surface is positioned adjacent to the inside surface of the flexible substrate with its front surface extending along at least a portion of the inside surface of the flexible substrate at the one or more locations including the plurality of holes. The interactive object includes one or more electronic components electrically coupled to the illuminated surface to control the illuminated surface to provide a visual output.

A portable light may comprise: a light body; a light source, an electrical switch for selectively energizing the light source, the light body having an opening through which the electrical switch can be actuated. A pivot pin pivotably mounts an actuator having an actuation feature that extends towards the opening for actuating the electrical switch when pivoted towards the light body. The light body has a receptacle in which the pivot pin is removably disposed. A retainer of a resilient material resiliently retains the pivot pin in the receptacle and resiliently deforms for removal of the pivot pin therefrom; whereby the actuator is removable and replaceable on the light body by removing the pivot pin. The light body may have a seal of resilient material in the opening of the light body. A user formable actuator of a curable material may be provided.
