The actual clear light clips for hanging Christmas tree lights outside are great and I've found different uses indoors for them. I hung one at the bottom of a wall to hold a power cord in place. I have another one attached to my TV holding a cord in place making my entertainment center less messy. With these projects however, I did NOT use the tape that was included. The tape included is white and I needed clear tape, which I was able to get at a home improvement store, since it does not need to be in extreme temperatures.
I'm hesitant to hang the clips outside first because I have colored trim and the white tape will stand out and look funny. Second, because the package says not to put the tape on rough surfaces, like brick, cement board or rough sawn wood. If I don't put the tape on the trim, it would be on the rough clapboard and I'm not sure I want that.
So I'm sticking with indoor uses for now!
