1. An optoelectronic arrangement for use in a transparent glazing element of a vehicle, the optoelectronic arrangement comprising:
at least one substantially transparent carrier layer;
at least one conductor layer comprising conductor paths provided on at least one side of said at least one substantially transparent carrier layer;
at least one light emitting element arranged on the at least one substantially transparent carrier layer and electrically coupled to conductor paths on said conductor layer;
at least one proximity and/or touch sensor arranged on said at least one substantially transparent carrier layer;
at least one optical layer bonded to said at least one substantially transparent carrier layer over the at least one light emitting element for diffusing light from each light emitting element into a light patch of substantially uniform illuminance and of greater diameter than the at least one light emitting element;
wherein the arrangement is couplable to a control module for controlling the operation of said at least one light emitting element in response to information from said at least one proximity and/or touch sensor; and
wherein said at least one optical layer comprises an array of optical segments on an input surface and an array of optical segments on an output surface, wherein the array of optical segments on the output surface are larger than the array of optical segments on the input surface.
