The bulb puller easily helps remove bulbs from the tight sockets. Some additional features are the Bulb and Fuse Tester. The LED Keeper Pro also includes a 9V battery. A Universal Replacement POD is included in the LED Keeper Pro kit as well. The POD assists with sets that do not have replaceable bulbs and can resolve socket issues.
