Abstract: A tell-tale construction includes an optical fiber ribbon that emits light along its length to make the tell-tale visible at night. The optical fiber ribbon is housed between a pair of plastic strips having the size, flexibility, and weight of a conventional tell-tale, and the plastic strips are transparent or translucent so that the light emitted from the ribbon is visible through the plastic. In a preferred embodiment, a light emitting diode is modified by forming a slot in its leading end so that a first end of the optical fiber ribbon is insertable into the slot, in alignment with the light-emitting anode of the LED. In other embodiments, a central light source is employed and optical fibers deliver light to each tell-tale to eliminate the need for a light source associated with each tell-tale.
