1. A retractable writing instrument with a light assembly comprising:
- (a) an elongated barrel having upper and lower ends with an aperture in said lower end;
(b) writing means disposed within the lower portion of said barrel having an upper end and a writing tip at its lower end;
(c) moving means for moving said writing means between a first position wherein said writing tip is retracted within said barrel and a second position wherein said writing tip extends outwardly of said aperture in its lower end;
(d) a battery having positive and negative terminals and disposed within the upper portion of said barrel;
(e) a lamp within said upper portion of said barrel for providing illumination of at least a segment of said upper portion, said lamp having a first contact electrically connected to one terminal of said battery and a second contact;
(f) a switch supported in said barrel for selectively effecting the connection of an electrical circuit between the other terminal of said battery and said second contact of said lamp, said switch being operably connected to said moving means and having(i) a switch-off position when said writing means is in said first position and in which said circuit is open to turn off said lamp, and(ii) a switch-on position when said writing means is in said second position and in which said circuit is closed to turn on said lamp.

Abstract
A retractable writing instrument such as a pen includes a light assembly in the upper portion of the barrel and a push button to extend and retract the writing tip at its lower end. In the upper portion of the barrel are a battery, a lamp, and a switch which selectively completes or breaks an electrical circuit between the battery and the lamp as a result of movement of the push button. The lamp illuminates a portion of the upper barrel which can serve to highlight advertising indicia on the barrel, or provide an indication of the position of the writing tip, or provide some other special effect.
