ABSTRACT:
A retractable pen with illumination means has coaxial upper and lower barrel members which consist of a conductive body. A conductor element and a light-emitting diode having two chips are fitted in the front part of the lower barrel member. The chips of the light-emitting diode are arranged on symmetrically sides of the writing tip. When the reservoir tube is fitted in the upper and lower barrel members, the conductor element is connected with cells placed in the rear end of the upper barrel member; thus, the light-emitting diode illuminates evenly.
