Just thought I'd add this. People are often warned about faulty Christmas Tree lights, or using too many plugs, but look what happened to our Christmas Tree light 'box'. It was a set that changed colour and flickered in different random pattens. Suddenly all the lights in the house dimmed and this set of lights all went out. We had three sets on the tree so may not have noticed if we hadn't been there. Luckily we were and immediately investigated to find the inside of the box had melted!
