Can someone tell my what these are called?

Fake icicles that you can turn on at night?

Hi, Yacdiel.
Thanks for the reply.
Wish I could help you further but I am at a loss.
Keep well.

If you are referring to what is hanging from all along the eaves about 12" to 18", those are fake icicles…really.

At least, they look like what some people put up here abouts.
