I have lights in the windows too

When these stop working the next set will be the LED kind we'll see if these survived the fall this year after I drag them in the house to thaw.

All I have been able to find online for hanging has been the plastic "gutter" clips. I do not have gutters so the clip instructions tell you to stick them under the shingles.

I'm sure the problem is the ice build up don't know what I can do about that though.
