Abstract: A damaged light bulb base extractor has a generally cylindrical, resilient, expandable base-engaging member mounted on a handle member. With the base-engaging member sandwiched between compression plates, relative movement of the compression plates toward each other compresses and expands the base-engaging member diametrically to engage and grip the interior sidewall of a light bulb base for extraction from a socket. Relative movement of the compression plates away from each other permits the base-engaging member to return to its initial unexpanded state for removal from a light bulb base. Extendable ribs on the external sidewall surface of an expandable base-engaging member can be used as a sole means of expanding the diameter of a base-engaging member or in conjunction with the compression plates to expand the diameter of the base-engaging member.
