A relay adapter circuit is electrically connected with the existing stop lamp and turn signal lamp systems of a motor vehicle and with the existing lamps on a trailer towed by the motor vehicle. The adapter is especially suited for installation where the vehicle has separate stop and turn signal lamp circuits on each side of the vehicle and the trailer has only a single lamp circuit on each side. The adapter achieves combined stop/turn signal capability in the trailer lamps.
