Abstract
There is described a lighting system for vehicles comprising light emitting diodes mounted on printed circuit boards (PCBs). Auxiliary components such as speakers are mounted on some of the PCBs lighting modules which are connected in an end-to-end relationship and which form light rows of the lighting system. Electrical traces for the auxiliary components form part of the PCBs. This results in a substantial reduction in or elimination of wiring. Connectors at each end of a PCB are compatible with the connectors on a neighboring PCB and are optionally connectable with a respective corresponding connector assembly of another lighting module in a direction substantially normal to the planar mounting surface of the PCB or in a direction substantially parallel to the planar mounting surface.
