Set of 100 UL light bulbs with a green cord.
Please ensure each bulb is seated properly and fully in its socket. Bulbs that have burned out should be easily detectible since the glass will be darkened around the broken filament. Burnt-out bulbs can cause overheating which will eventually cause a series of lights to shut down. We recommend replacing the burnt-out bulbs as soon as possible. Unplug the strand and replace the bad bulb with a new bulb of the same size and the same voltage rating (2.5 Volt).
