Anthony decorated a tree in his front yard with strings of  5mm LED Christmas lights in red and green.

These pictures above show the wonderful results.  The trees are wrapped snugly without any kind of hardware to keep them in place.

The green lights are connected to one side of the extension cord splitter and the red lights to another.

Note, different colors of LED light strings should ideally be run in separate circuits in these types of installations since their strings have different current draws.
