Abstract: An apparatus including an electrical cable provided with light emitters along its length for visual communication of its position/extent and of statuses of the apparatus, said statuses including at least statuses related an insulation resistance between conductors of the electrical cable. The apparatus is provided with a power unit enabling status updates and light emission also when the electrical cable is disconnected and thus not in use.

Abstract: An apparatus and a method for indicating a status of an electrical cable, in particular in a power system of a vehicle the apparatus being configured to be attached to the electrical cable, the apparatus comprising: voltage measuring means for continuously measuring a voltage level of the electrical cable, at least one light-emitting indicator configured to be visibly attached to the electrical cable, control means for controlling emission of light from the at least one light-emitting indicator based on the measured voltage of the electrical cable. The apparatus is adapted to be powered by a power source other than the electrical cable.
