Abstract: Jumper cables include a housing with first and second pairs of cables extending therefrom. On an upper surface of the housing are a pair of dual-color LEDs, each associated with one of the pairs of cables. Circuitry within the housing causes each LED to illuminate in one of two discrete colors when the polarity of the cables is reversed. A rotary isolation dial with multiple visual indicators allow a user to independently verify that the polarity of each pair of cables is correct before establishing electrical communication between two batteries. The LED circuits include a surge suppressor that protects the rescuing vehicle and the disabled vehicle's electrical system from alternator load dump when the rescuing vehicle's engine is running. Adapters allow an auxiliary power source to be coupled with the jumper cables in the event the dead battery is incapable of powering the LEDs and alarms.
