The inner wall also defines a channel that is positioned longitudinally through the sleeve and configured for insertion a shaft of a tool. The sleeve is reversibly couplable to the shaft. A power module is coupled to the sleeve and positioned in the interior space. A plurality of lights is coupled to a first end of the sleeve. A switch, which is coupled to the outer, is operationally coupled to the power module and the plurality of lights. The switch is configured for activation by a user to couple the power module to the lights. The lights are configured to illuminate a work space at a working end of the shaft of the tool. ## Claims ### Claim 1 A lighted tool shaft attachment comprising: a sleeve comprising an inner wall and an outer wall defining an interior space, said inner wall defining a channel positioned longitudinally through said sleeve, said sleeve being reversibly couplable to a shaft of a tool; a power module coupled to said sleeve and positioned in said interior space; a plurality of lights coupled to a first end of said sleeve; a switch coupled to said outer wall of said sleeve, said switch being operationally coupled to said power module and said plurality of lights; and wherein said channel is configured for insertion of a shaft of a tool such that said shell is coupled to the shaft, wherein said switch is positioned on said shell such that said switch is configured for activation by a user, wherein said switch is positioned to couple said power module to said lights, wherein said lights are positioned on said shell such that said lights are configured to illuminate a work space at a working end of the shaft of the tool ### Claim 2 (depends on 1) The attachment of claim 1, further including said channel being substantially complementary to the shaft of the tool. ### Claim 3 (depends on 1) The attachment of claim 1, further including said sleeve comprising metal. ### Claim 4 (depends on 1) The attachment of claim 1, further including said sleeve comprising plastic. ### Claim 5 (depends on 1) The attachment of claim 1, further including said power module comprising at least one battery. ### Claim 6 (depends on 51) The attachment of claim 51, further including said battery being rechargeable. ### Claim 7 (depends on 1) The attachment of claim 1, further including said lights comprising light emitting diodes. ### Claim 8 (depends on 1) The attachment of claim 1, further including said plurality of lights comprising from two to ten said lights. ### Claim 9 (depends on 8) The attachment of claim 8, further including said plurality of lights comprising from four to eight said lights. ### Claim 10 (depends on 9) The attachment of claim 9, further including said plurality of lights comprising six said lights. ### Claim 11 (depends on 1) The attachment of claim 1, further including said switch comprising a button, said button being depressible, wherein said button is depressible a first time to electrically couple said lights to said power module and wherein said button is depressible a second time to decouple said lights from said power module. ### Claim 12 (depends on 11) The attachment of claim 11, further including said button being ovally shaped. ### Claim 13 (depends on 1) The attachment of claim 1, further including a pair of slots positioned in said inner wall and extending from said first end to said second end, wherein said slots are positioned in said inner wall such that said slots are configured for insertion of a head of a flathead screwdriver. ### Claim 14 (depends on 1) The attachment of claim 1, further comprising: a compression collar threadably couplable to a second end of said sleeve; a pair of slits positioned in said sleeve adjacent to said second end, said slits extending toward said first end; and wherein said slits are positioned to at least partially close as said compression collar is tightened on said second end of said sleeve, wherein said sleeve is coupled to the shaft of the tool, ### Claim 15 (depends on 14) The attachment of claim 14, further comprising: a pair of slots positioned in said inner wall and extending from said first end to said second end; said slits being positioned singly in said slots; and said compression collar comprising a nut, said nut being hexagonally shaped when viewed axially. ### Claim 16 a port coupled to said outer wall, said port being operationally coupled to said battery, said port being configured for coupling to a power source, wherein said port is positioned on said sleeve such that said port is configured for coupling to a power source to recharge said battery. ### Claim 17 A lighted tool shaft attachment comprising: a sleeve comprising an inner wall and an outer wall defining an interior space, said inner wall defining a channel positioned longitudinally through said sleeve, said sleeve being reversibly couplable to a shaft of a tool, said channel being substantially complementary to the shaft of the tool, said sleeve comprising metal; a power module coupled to said sleeve and positioned in said interior space, said power module comprising at least one battery, said battery being rechargeable; a plurality of lights coupled to a first end of said sleeve, said lights comprising light emitting diodes, said plurality of lights comprising from two to ten said lights, said plurality of lights comprising from four to eight said lights, said plurality of lights comprising six said lights; a switch coupled to said outer wall of said sleeve, said switch being operationally coupled to said power module and said plurality of lights, said switch comprising a button, said button being depressible, wherein said button is depressible a first time to electrically couple said lights to said power module and wherein said button is depressible a second time to decouple said lights from said power module, said button being ovally shaped; a pair of slots positioned in said inner wall and extending from said first end to said second end, wherein said slots are positioned in said inner wall such that said slots are configured for insertion of a head of a flathead screwdriver; a compression collar threadably couplable to a second end of said sleeve, said compression collar comprising a nut, said nut being hexagonally shaped when viewed axially, a pair of slits positioned in said sleeve adjacent to said second end, said slits extending toward said first end, wherein said slits are positioned to at least partially close as said compression collar is tightened on said second end of said sleeve, wherein said sleeve is coupled to the shaft of the tool, said slits being positioned singly in said slots; a port coupled to said outer wall, said port being operationally coupled to said battery, said port being configured for coupling to a power source, wherein said port is positioned on said sleeve such that said port is configured for coupling to a power source to recharge said battery; and wherein said channel is configured for insertion of a shaft of a tool, wherein said second end of said shell is positioned for coupling to said compression collar such that said shell is coupled to the shaft, wherein said switch is positioned on said shell such that said switch is configured for activation by a user, wherein said switch is positioned to electrically couple said power module to said lights, wherein said lights are positioned on said shell such that said lights are configured to illuminate a work space at a working end of the shaft of the tool. ### Claim 18 (depends on 17) The attachment of claim 17, further including said sleeve comprising plastic.
