Abstract
A repair device for fixing a malfunctioning shunt across a failed filament in a light bulb in a group of series-connected miniature decorative bulbs includes a piezoelectric pulse generator producing one or more pulses of a magnitude greater than the standard AC power line voltage. A connector receives the pulses from the pulse generator and supplies them to the group of series-connected miniature decorative bulbs.
