PLYMOUTH, Minnesota (KARE) -- It's one of the most common holiday frustrations - plugging in that strand of lights only to find them fizzle.
A product on the market, LightKeeper Pro, claims to restore failed light sets in a few easy steps, just "plug, click and fix" according to a company commercial.
"I have had quite a few customers come in that swear by them, say they work great," says hardware store manager Jim Lee.
Lee agreed to test the LightKeeper Pro, using customer's recycled light strands cast off at the store. He used the red handheld gun, which according to directions, emits an electrical pulse to a defective bulb, restoring electrical current and reigniting the strand.
