No touch or motion lights, but I've noticed this morning that the buzzing all but disappeared when the AC wasn't running in the early morning. After work this evening, I will take the little digital radio around the house looking for the sources. Unplug all wall warts, turn off all fluorescent lights, shut down the AC, shut off the wireless and wireless phones, then turn them back on one at a time and see what happens.
