Abstract
A flashlight has a casing extending along an axis, formed with a screwthread, and holding a battery having two poles. A light-emitting diode has a light-emitting head and a first and second integral lead wires. A holder is formed with first and second separate throughgoing holes, a seat into which the holes open and in which the diode head is fitted with the first and second wires extending outward through the respective first and second holes out of contact with each other, a reflector adjacent the seat, and a screwthread. The holder is fitted to the casing with the screwthread of the holder operatively engaged with the screwthread of the casing and the first wire pressed directly against one of the poles of the battery.
