Light Keeper Pro

The complete tool to fix icandescent light sets, which includes a bulb tester, fuse tester, batteries installed, and ten spare bulbs (located in handle). Defective Bulb shunts cause most light set failures. Simply plug your LightKeeper Pro into the light set and pull the trigger. The LightKeeper Pro sends a pulse through the light set, finds the bad bulb, and fixes the shunt—allowing the light set to work properly.
