Decorative light strings and repair device

摘要: One or more strings of decorative lights are supplied with power by converting a standard residential electrical voltage to low-voltage, and supplying the low-voltage at least one pair parallel conductors having multiple connected along lengths thereof, each lights, groups being in across conductors. A repair device for fixing malfunctioning shunt failed filament light bulb group series-connected miniature bulbs includes high-voltage pulse generator producing pulses magnitude greater than AC line voltage. connector receives from supplies them bulbs. The may be piezoelectric generator, battery-powered electronic and/or an AC-powered generator.
