How To Use A Christmas Bulb Tester

Check out an easy and affordable tool that helps identify the problem fast and get your lights up and running in minutes.


About The Tool

The LED Keeper is the only kit able to diagnose and repair LED light sets. The tool contains a bulb tester, fuse tester, bulb puller, and even complete with a 9 volt battery. Two place markers are included to assist in testing, along with two Universal Bulb Replacement PODs for those sets with non-replaceable bulbs.

How It Works

Defective Bulb shunts cause most light set failures. Place the 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.
