Method of making a vehicle light and related vehicle light

A vehicle light comprising

• a container body delimited by a first perimetral profile,
• a lenticular body having an outer side wall, an inner side wall, and an abutment edge, delimited by a second perimetral profile,
• wherein the first and second perimetral profile of the container body and of the lenticular body are at least partially counter-shaped to each other so as to interface at a welding interface of the abutment edge of the lenticular body,
• said welding being a laser-type welding,
• wherein the container body delimits a containment seat which houses at least one light source and the lenticular body is applied on the container body so as to close said containment seat,
• wherein the abutment edge is offset from the outer side wall, and the abutment edge is offset from the inner side wall by a recess facing the containment seat such that the abutment edge is between the outer and inner side wall,
• wherein said abutment edge of the lenticular body includes a redirection surface, wherein the redirection surface includes a curvilinear wall having at least one parabolic profile with respect to a cross-section plane perpendicular to the welding interface and perpendicular to a plane tangent to an inner side wall of the lenticular body, opposite said outer side wall, in which a focus of said parabolic profile is positioned in the vicinity of said welding interface,
• the redirection surface adapted to receive laser beams emitted by a laser source external to the at least one light source and to the containment seat, to reflect the laser beams satisfying the condition of total internal reflection and to direct the laser beams towards said welding interface,
• said laser beams impacting on the outer side wall of the lenticular body, opposite the containment seat and, after passing through the lenticular body, directly or by at least one reflection, impacting on said redirection surface, wherein the lenticular body and the container body are welded together at the welding interface.
