There is a combination of twinkle lights and steady-on lights on this wreath. Both sets of lights are powered by one battery pack.
Here is a list of the parts that are used:
1) An AA battery box.
2) A PL12 wire splitter connected to the battery box.
3) A TW50S light strand to provide the twinkle lights.
4) A C100S light strand to provide the steady-on lights.
