Abstract
A method of manufacturing an automotive light including the steps of: providing at least one laser diode emitting a light beam with a characteristic emission spectrum; providing a container body delimited by a first perimetral profile; providing a molded lenticular body delimited by a second perimetral profile and having at least first and second overlapping integral layers with different transmittance values in relation to the laser emission spectrum; at least partially associating the perimetral profiles; and at least partially welding at the perimetral profiles with the laser, wherein the laser beam is routed towards the perimetral profiles so as to reach the first perimetral profile after passing through at least one of the layers of the lenticular body, and wherein the container body acts as an absorbing member in relation to the light beam and the lenticular body acts as a transmissive member of the light beam.
