Abstract
Disclosed is a writing implement with self-contained illumination including a barrel comprised of first and second electrically conductive sections insulated one from the other by an annular band. One section carries a lens, a writing point and a lamp, coaxially of the barrel with the lamp lying in electrical contact with the one section. The barrel also defines a battery compartment. A cap is formed of electrically conductive material and, when the writing implement is not in use, closes over the writing point about the first section. When the writing implement is to be used and illumination is not needed, the cap is disposed about the first section at the opposite end of the barrel and retained. Should illumination be necessary, the cap is pushed beyond the insulating band to electrically connect the two sections and complete an electrical circuit to the lamp to energize the lamp and illuminate the area surrounding the writing point through the lens.
