For normal light bulbs, there is usually no special tool required to remove them. For a stuck light bulb, 2 feet of duct tape creates handles to help remove it. Also, a stuck or broken bulb requires the repairman to wear thick leather gloves and safety goggles.
Some hardware stores sell special broken bulb extractors with rubber tips that help extract the base of the bulb. A pair of needle-nose pliers also helps grip a broken bulb and allows the repairman to turn it. An unpeeled and uncooked potato also helps extract a broken bulb from a socket. For this method, repairmen must peel a cylinder shape into the spud that fits into the bulb, and then use the unpeeled part of the potato to grip and remove the bulb.
