Christmas Light Tester/Repair Gun

Finds and fixes problems with faulty miniature light sets

New patented technology brings you an easy-to-use system for detecting and repairing those miniature light sets that cause you so much grief each year. A built-in continuity detector, with audible tone, helps locate the source of the power interruption. Plug light set into Repair Gun and squeeze the trigger to send a pulse through the defective light set. This fixes the circuit, allowing the current to flow. There is also a bulb and fuse tester; a bulb remover; LED light to help illuminate working area; spare bulbs and detailed instructions. Operates on three (included) replaceable 1.5 volt button cell batteries.
