• Compare and contrast troubleshooting strategies for decorative lighting.
• Discuss the pros and cons of each configuration.

There  are typically two kinds of circuits use in decorative lighting systems.  The first, being series circuits which just conducts power to each light  sequentially down the strand. The second, parallel circuits, is wired  alternatingly so that if a few bulbs go out, it won’t shut off power to  the rest.

Honestly, I’ve always had very simple lighting systems on and in my  house. Typically, for the tree we just have it on a flash setting with a  timer. For outside, usually, we just have constant lights that get  turned off during the day and come on when it is dark, for me 6-7p.m.  Eventually, I want to have a lightshow, I think that would be cool  especially, taking inspiration from some of the videos I’ve seen with  drones.
