In a vehicle lamp, light emitting diodes that emit light are disposed on an inner side of a transparent surface cover. A conductive reflector that reflects the light emitted from the light emitting diodes toward the surface cover is provided between the light emitting diodes and the surface cover. The reflector is disposed so as to be in proximity to the light emitting diodes. A grounding connection terminal is provided on the reflector. The grounding connection terminal is connected to a vehicle body.

A lamp assembly and to a method for assembling the lamp assembly with a heat sink, a base plate for holding at least one light source, and a reflector. A light that can be generated by the light source can be directed into this reflector and wherein the heat sink has a mounting surface on which the base plate and the reflector are arranged one on top of the other. A common mounting opening extends through the heat sink, the base plate, and the reflector, wherein a spring element and a tension element are arranged in this opening and wherein the heat sink, the base plate, and the reflector are clamped one on top of the other with a clamping force by means of the spring element. The clamping force is applied on the spring element by means of the tension element.
