An electrical power source, which may take the form of a battery, is disposed within the device and a selectively activated light source, which may take the form of an LED, is operably coupled with the power source. In some embodiments, the light source is selectively activated and deactivated by relative rotation of the first and second housing members. ## Claims ### Claim 1 An illumination device comprising: a first housing member having a threaded stem; a second housing member having a threaded bore wherein the threaded stem and the threaded bore are positioned at opposite ends of the device when the first and second housing members are coupled together; an electrical power source coupled with the device; and a selectively activated light source operably coupled with the power source. ### Claim 2 (depends on 1) The device of claim 1 wherein the threaded stem and the threaded bore are concentrically disposed relative to a common axis and wherein the light source emits light from the second housing member at a location radially outwardly of the threaded bore. ### Claim 3 (depends on 2) The device of claim 2 wherein the second housing defines at least one opening through which the light source emits light. ### Claim 4 (depends on 2) The device of claim 2 wherein the second housing comprises a clear material through which the light source emits light. ### Claim 5 (depends on 1) The device of claim 1 wherein the light source is selectively activated and deactivated by relatively rotating the first and second housing members. ### Claim 6 (depends on 5) The device of claim 5 wherein the first and second housing members are threadingly engaged. ### Claim 7 (depends on 6) The device of claim 6 wherein the electrical power source comprises a battery and the light source comprises an LED and wherein relative rotation of the first and second housing members opens and closes an electrical circuit operably coupling the battery and the LED and thereby selectively activates the LED. ### Claim 8 (depends on 7) The device of claim 7 wherein at least one of the first and second housing members defines a portion of the electrical circuit operably coupling the battery and the LED. ### Claim 9 (depends on 8) The device of claim 8 wherein the first and second housing members are at least partially formed of anodized aluminum and wherein the at least one housing member defining a portion of the electrical circuit includes first and second non-anodized aluminum surfaces forming electrical contact surfaces for electrically communicating with the electrical circuit, the first non-anodized aluminum surface being selectively engageable with an opposing electrical contact surface by relative rotation of the first and second housing members to thereby open and close the electrical circuit coupling the battery and the LED. ### Claim 10 (depends on 9) The device of claim 9 further comprising an O-ring disposed between and engaging each of the first and second housing members. ### Claim 11 (depends on 9) The device of claim 9 wherein the threaded stem and the threaded bore have a common diameter and a common pitch whereby the threaded stem and threaded bore define a first thread configuration and are threadingly engageable. ### Claim 12 (depends on 11) The device of claim 11 further comprising an adapter having a second threaded bore and a second threaded stem disposed opposite the second threaded bore, wherein one of the second threaded bore and the second threaded stem defines a thread with the first thread configuration and is thereby engageable with one of the threaded stem and the threaded bore of the device and the other of the second threaded bore and the second threaded stem defines a thread having a second thread configuration that is incompatible with the threaded stem and threaded bore of the device. ### Claim 13 (depends on 12) The device of claim 12 wherein the second threaded bore is engageable with the threaded stem of the first housing member. ### Claim 14 (depends on 13) The device of claim 13 further comprising a second adapter defining a third threaded bore and a third threaded stem disposed opposite the third threaded bore, the third threaded bore being engageable with the threaded stem of the first housing member and the third threaded stem defining a third thread configuration incompatible with both the first and second thread configurations. ### Claim 15 An illumination device comprising: a first housing member having a threaded stem; a second housing member having a threaded bore wherein the first and second housing members are threadingly coupleable and the threaded stem and the threaded bore are positioned at opposite ends of the device when the first and second housing members are threadingly coupled together; a battery disposed within the device; and a light source operably coupled with the power source wherein the light source is selectively activated and deactivated by relatively rotating the first and second housing members. ### Claim 16 (depends on 15) The device of claim 15 wherein the threaded stem and the threaded bore have a common diameter and a common pitch whereby the threaded stem and threaded bore define a first thread configuration and are threadingly engageable. ### Claim 17 (depends on 16) The device of claim 16 wherein the second housing defines at least one opening through which the light source emits light. ### Claim 18 (depends on 16) The device of claim 16 wherein the second housing comprises a clear material through which the light source emits light. ### Claim 19 (depends on 16) The device of claim 16 wherein the first and second housing members are at least partially formed of anodized aluminum and wherein at least one of the first and second housing members defines a portion of an electrical circuit operably coupling the battery and the light source, the at least one housing member including first and second non-anodized aluminum surfaces forming electrical contact surfaces for electrically communicating with the electrical circuit, the first electrical contact surface being selectively engageable with an opposing electrical contact surface by relative rotation of the first and second housing members to thereby open and close the electrical circuit coupling the battery and the light source. ### Claim 20 (depends on 19) The device of claim 19 wherein the relative rotation of the first and second housing members defines an axis and the threaded bore and the threaded stem are concentrically disposed relative to the axis; wherein the light source comprises an LED mounted on a printed circuit board defining the opposing electrical contact surface; and wherein the electrical circuit comprises a spring, the spring biasing the printed circuit board away from the first non-anodized aluminum surface and wherein the device further comprises an O-ring disposed between and engaging each of the first and second housing members.
