The backup alarm could be wired to the reverse switch or to one of the reverse light bulbs. Since it comes on when you turn the headlights on I would assume that it is wired to the reverse light bulb and there is a short causing the tail light to power the backup alarm. When you turn the lights on do the reverse lights turn on also?
