In a tool for extracting and inserting light bulbs, it is known to have a cup-shaped gripper made out of an elastic material attached to a support having a clear hole running vertically through the center with which to attach said tool to a pole. In this invention, the gripper is provided along its upper edge with a number of vertically-aligned and equally-spaced clear slots which facilitate expansion of the gripper when a bulb is inserted into it and horizontally- aligned beads or ridges on the inside surface with which to grip and locate the bulb in the gripper. The support is adapted to be held and manipulated comfortably in the hand, having a generally square profile with rounded edges and a textured handgrip surface along it's length. A splined and tapered socket is provided in the base of the support to receive a matching connector mounted upon a pole. A self- storing hinged hang-up loop is located just above the base of the support. These improvements allow the tool to be more convenient, easier, and safer for the operator to use. They also extend the tool's range of useful operation to include handheld operation and use of the same size of tool for a variety of light bulb shapes, reducing the number of different tools required to handle the wide variety of screw-type light bulbs in common usage. The present design allows economic production of a tool which is suited to both household and industrial applications.
