1. A lighting strip, comprising:
a strip-shaped printed circuit board which includes:
one or more perforated lines at which the printed circuit board length may be adjusted by breaking off an end portion of a printed circuit board;
a first layer having a first set of conductive tracks;
a second layer provided over the first layer, having a second set of conductive tracks corresponding to the first set of conductive tracks, wherein each conductive track of the second set is vertically aligned and positioned over the corresponding conductive track of the first set; and
a third layer provided over the second layer, having an array of contact terminals; and
a plurality of lighting elements disposed along the lighting strip, each electrically connected to a respective pair of the contact terminals;
wherein the lighting strip comprises a set of vias connecting each conductive track of the first set to the corresponding conductive track of the second set.
