Tiffany, the hummers by me are always using the overhead phone and electric wires just to sit and rest. Or more likely to lord over their domain, check for any intruders and make sure all is as it should be for them. They even like the fatter wires and will sit up there for 15 minutes at a time taking a quick snooze. I'm sure they'd like using the LED strings too, they even sit on the vines that end up draped from the corner hanging planters to the one with the trellis in it, they think it's their own jungle gym.
