In one sentence, describe what the following article is about: Christmas tree lights can be end to end or stacked. End to end is also known as string to string.

Summary: Make sure all your lights are compatible. Check the wattage of the bulbs. Plug in your lights before removing them from the box. Use miniature clear lights as base lighting.
