ABSTRACT:
An illuminating writing instrument for providing an illuminated writing surface and a method for its manufacture. The illuminating writing instrument includes a housing that defines an enclosure that holds the components of the illuminating instrument. The housing has an end that supports a writing point and an end that supports an upper portion having a transparent window portion that allows light to pass therethrough. The housing also encloses an electrical circuit that includes a power source, a switch, and a light source such that when the switch is activated, the light source produces illumination. The upper portion of the housing also includes a reflector that reflects light from the light source through the transparent window portion to illuminate a writing surface. The illuminating writing instrument can also include at least one optic fiber that extends from an area adjacent the light source, along a portion of the length of the housing, and to a location adjacent the writing point to illuminate a writing surface. The illuminating writing instrument can also include a replaceable writing means, a replaceable power source, and a replaceable light source. The illuminating writing instrument can also include a rechargeable power source and a device to afford recharging to the rechargeable power source.
