Abstract: A lamp unit for a motor vehicle includes a light source, a substantially plano-convex projection lens, and an identification symbol. The projection lens has the configuration of a spherical segment and a central region, and the identification symbol is disposed in the central region of the planar side of the projection lens. The planar side of the lens faces the light source. A method of making a lamp unit for a motor vehicle includes disposing an identification symbol in a central region of a planar side of a substantially plano-convex projection lens of the lamp unit, wherein the planar side of the lens faces a light source.
