Abstract

A jumper cable assembly has a pair of clamps at both ends for parallel connection to a weak and a strong battery for starting a motor. Along the side of the assembly is mounted an elongate, flexible electroluminescent element that is powered when either end of the assembly is connected to a battery. The assembly lights up along its length to thereby avoid tripping over it when it is being used in the dark.

Claims

1. A flexible jumper cable assembly comprising:

a) an elongate positive wire having battery connections at both ends;

b) an elongate negative wire having battery connections at both ends;

c) an elongate, flexible electroluminescent element disposed alongside the positive and negative wires to move therewith; and

d) an electroluminescent power supply having an input connected to the negative and positive wires and an output connected to the electroluminescent element at one end thereof to cause the electroluminescent element to emit light along its length to thereby illuminate the assembly when a battery is connected to the positive and negative wires.

2. The jumper cable assembly according to claim 1 in which the electroluminescent element is spirally wound on the wires.

3. The jumper cable assembly according to claim 1 further comprising an audible signal generator that emits an audible signal when the wires are incorrectly connected to the battery.

4. A flexible jumper cable assembly comprising:

a) an elongate, continuous positive wire of a particular length having a battery connection at each end;

b) an elongate, continuous negative wire of substantially the same particular length having a battery connection at each end;

c) an elongate flexible electroluminescent element disposed along a major portion of the positive and negative wires to move with the positive and negative wires and to emit light along its length when electric power is applied to one end; and

d) an electroluminescent power supply having an input connected to the negative and positive wires and an output connected to one end of the electroluminescent element to thereby illuminate a major portion of the assembly when at least one battery is connected to the positive and negative wires.

5. The jumper cable assembly according to claim 4 in which the electroluminescent element is spirally wound on the wires.

6. The jumper cable assembly according to claim 5 further comprising an audible signal generator that emits an audible signal when the wires are incorrectly connected to the at least one battery.

7. The jumper cable assembly according to claim 4 further comprising an audible signal generator that emits an audible signal when the wires are incorrectly connected to the at least one battery.
