UFO Sighting in Saint George, Utah on July 22nd 2015 – two twin bright orange lights, closely syncronized, but separation of lights to great to be a single aircraft. May be two helicopters?

Looking toward crescent moon SW from our patio. Noticed two bright orange horizontal lights...Left light went dark, then the right light. Approx. 30 seconds later, both lights returned at same location and elevation. Both went dark again after about 10 seconds. No additional sightings.
