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 at least one light emitting diodes (LED) that is powered when either end of the assembly is connected with correct polarity to a battery. The at least one LED may illuminate a fiber optic bundle disposed along the length of the assembly. The assembly lights up along its length to thereby avoid tripping over it when it is being used in the dark. When the assembly is connected to a battery with the wrong polarity, the LED will not light up. In an alternative embodiment, a plurality of LED's are disposed along the length of the assembly. The light emitted may be made to flash or change color to indicate the voltage on the battery to which it is connected.
