Jumper cables
First Claim
1. A battery jumper cable for polarized connection of a source battery to a destination battery, comprising:
- (a) two insulated cables each having first and second ends,(b) battery attachment means at each end of said cables,(c) a first polarity indicating means at the second ends of one of the cables for indicating the polarity of the source battery when the first ends of said cables are arbitrarily connected thereto,(d) a first and second probe at the second ends of said cables and electrically insulated therefrom, and(e) a second polarity indicating means at the second end of one of said cables for indicating the polarity of said destination battery when said first and second probes are arbitrarily connected thereto prior to polarized connection of the second ends of the cables to the destination battery.

Abstract
A pair of improved jumper cables one end of which automatically lights when the other is arbitrarily connected to a source battery and also automatically indicates the polarity of the source battery by means of light emitting diodes. Also when a pair of probes at the lighted end is arbitrarily connected to the destination battery, the polarity of the destination battery is automatically indicated by means of light emitting diodes. The polarities of the source battery and the destination battery are displayed together on the face of one of the clamps at the lighted end. By a comparison of the indicated polarities the correct connection can be made.
