I only have lights on my tree although I did put lights round the window on the inside a couple of times.
The residents of some streets round here go the 'whole hog' when decorating the outside of their hiomes, so much so that it is a local attraction for a while and they collect money for charity from the 'toursists'.
I have to say that some of the decorations you can but are a bit grosse....inflatable Santas and snowmen. I do like the lights though and every year they seem to be more hi-tech and sparkly.
When I was a kid, we had tiny 'real' candles in holders on the tree
