ABSTRACT:
A two-piece connector for battery jumper cables wherein the connector portions each indicate the positive and negative battery terminals to which the cables from the connector are to be connected. The connector further includes a two state LED device which provides a green light when the cables are connected to a battery with polarity in the manner stated on the connector and a red light when the polarity is reversed. The circuitry, therefore, is contained directly in each connector half. The connector halves are hermaphroditic so that they can not be connected in reverse polarity condition.
