Abstract
Abstract A pilot light arrangement for a hand-held appliance such as a curling and styling iron is disclosed, wherein the arrangement facilitates convenient visual inspection to see if the appliance is operating. The arrangement includes a pilot light mounted within a housing portion of the appliance, and a fiber optic bundle which extends through a swivel cord mount of the appliance. The fiber optic bundle is positioned in light-transmitting relation with the pilot light, with the end of the fiber optic bundle positioned at the exterior of the appliance being readily visible irrespective of the orientation of the swivel cord mount with respect to the appliance housing.
