Christmas lights are specified as either indoor (can only be used indoor) or outdoor (can be used either indoor or outdoor). All our sets come with a supply of spare bulbs. All our light sets are from reputable manufacturers and of good quality. All are tested to ensure they work properly before being sent out. If you require spare bulbs for other sets contact us with as much information as possible about the bulbs you require.
