Our mini light light set is reminiscent of an old fashioned light set that you may have had on the Christmas tree growing up or still use today on your one of a kind tree. What we like to call old school with new age technology that still looks classic. What is so great about these mini light strings is if one bulb goes out the rest stay lit because of the shunt that is manufactured inside each bulb that makes the power transfer to the next bulb regardless if its burnt out. This process is called "series parallel".
