ABSTRACT:
An electrical circuit for adapting the independent brake lights and turn signal lights on a towing vehicle to the combined brake and turn signal lights on an associated trailer. An isolation network and a first CMOS exclusive OR integrated circuit are connected between the right turn signal light connection and brake light connection of the towing vehicle and the combined right turn signal and brake light connection on the trailer. An isolation network and a second CMOS exclusive OR integrated circuit are similarly connected between the left turn signal light connection and brake light connection of the towing vehicle and the combined left turn signal and brake light connection on the trailer. The isolation network prevents feedback from the electrical lighting system of the trailer to the electrical lighting system of the towing vehicle.
