A vehicle lamp includes a lamp housing having an inner space and a welding surface, and a cover disposed adjacent to another vehicle lamp, and configured to cover the inner space and join to the lamp housing by laser welding. The cover includes a design surface in which an outer surface of an outer peripheral portion is formed as a curved surface and a welding leg that protrudes from a portion near the outer peripheral portion in the design surface. An annular portion on an inner peripheral side of the curved surface on an outer surface of the design surface is formed as a laser light incident surface. The curved surface is positioned on an outer peripheral side from an intersection point of a virtual line and the outer surface of the design.

A vehicle light having a container body having a first perimetral profile, a lenticular body, having a second perimetral profile, wherein the first and second perimetral profile of the container body and the lenticular body are at least partially counter-shaped to each other in order to interface at a welding interface of an abutment edge of the lenticular body. The container body delimits a containment seat that houses a light source and the lenticular body is applied to the container body so as to close the containment seat. A redirection surface is adapted to receive laser beams, to concentrate and reflect them towards the welding interface. The redirection surface is arranged on an inner face of the abutment edge, the inner face facing the containment seat and incident with the welding interface. A method of making the vehicle light is also disclosed.
