Abstract
Abstract The cable from a travel trailer is disconnected from a mating connector of a towing vehicle. The trailer cable is then plugged into a flasher module to cause flashing of the trailer running, side and overhead lights. Energization of the flashing lights occurs from a battery in the trailer, totally independent from the battery of the towing vehicle.
