The head unit comprises a grasping mechanism configured to engage a light bulb, a control switch and a rotation mechanism. The control switch configured to cause the grasping mechanism to become secured to a light bulb, and to cause the rotation mechanism to automatically detect when a light bulb is secured to the grasping mechanism and then rotate the grasping unit and the secured light bulb in a first direction based on the position of the control switch. The tool further comprises an arm unit for positioning the grasping mechanism in a desired configuration to engage the light bulb, wherein the arm member is coupled to the grasping mechanism. ## Claims ### Claim 1 A tool for inserting a light bulb comprising: a. a head unit to hold and used to turn the light bulb; and b. a sensor to sense when the light bulb is tightened into a socket. ### Claim 2 (depends on 1) The tool according to claim 1 wherein the tool further comprises an arm unit comprising one or more elbow interfaces having an upper and lower arm coupled to each other wherein the upper and lower arms are able to rotate with respect to each other. ### Claim 3 (depends on 2) The tool according to claim 2 wherein the elbow interfaces further comprise a lock wherein the lock allows the user to selectively configure the angle between the upper and lower arms of the elbow interfaces. ### Claim 4 (depends on 2) The tool according to claim 2 wherein the tool further comprises a number of first and second fasteners wherein the first fasteners comprise a release lever and a reception cavity and the second fasteners comprise a protruding member, wherein the protruding members is configured to automatically lock onto the cavities until the release levers are slid by the user. ### Claim 5 (depends on 4) The tool according to claim 4 wherein the first and second fasteners are used to selectively detachably couple an extendable pole, the head unit and the arm unit together. ### Claim 6 (depends on 1) The tool according to claim 1 wherein the head unit comprises a grasping mechanism for grasping the light bulb. ### Claim 7 (depends on 6) The tool according to claim 6 wherein the grasping mechanism comprises a suction cup wherein the suction cup is sufficiently thin such that it is able to effectively suction to any size light bulb. ### Claim 8 (depends on 6) The tool according to claim 6 wherein the grasping mechanism further comprises a stabilizing ring configured to visually aid the user in centering the suction cup on a light bulb. ### Claim 9 (depends on 8) The tool according to claim 8 wherein the stabilizing ring is configured to fold backwards. ### Claim 10 (depends on 1) The tool according to claim 1 wherein the head unit detects that a light bulb is coupled to the head and rotates the light bulb in a first direction based on a position of a control switch. ### Claim 11 (depends on 10) The tool according to claim 10 wherein the control switch comprises three states wherein one state causes the light bulb to rotate in the first direction and another state causes the light bulb to rotate in the opposite direction. ### Claim 12 (depends on 1) The tool according to claim 1 wherein the head unit further comprises a release button that is configured to release a light bulb that had been secured to the grasping mechanism. ### Claim 13 A tool for inserting a light bulb comprising: a. a unit for holding and rotating a light bulb; and b. a sensor for sensing that the light bulb is tightened into a socket. ### Claim 14 (depends on 13) The tool according to claim 13 wherein the unit detects that a light bulb is coupled to the unit and rotates the light bulb in a first direction based on a position of a control switch. ### Claim 15 (depends on 13) The tool according to claim 13 wherein the unit is configured to couple to an extendable pole. ### Claim 16 A method of inserting a light bulb into a socket using a tool comprising: a. rotating the light bulb into the socket; b. sensing that the light bulb has been tightened into the socket; and c. stopping rotation of the tool when it is sensed that the light bulb has been tightened into the socket. ### Claim 17 (depends on 16) The method according to claim 16 wherein sensing that the light bulb has been screwed in all of the way comprises sensing a pre-determined rotational resistance. ### Claim 18 (depends on 17) The method according to claim 17 wherein the light bulb is released from the tool when the pre-determined rotational resistance is sensed. ### Claim 19 (depends on 16) The method according to claim 16 wherein the light bulb is rotated when it is sensed that the tool has grasped the light bulb.
