An elastic tube alignment system for the mating an emblem lens to an outer bezel utilizing the principle of elastic averaging. A plurality of geometrically separated elastic tube (male) alignment features are disposed on a first side of the emblem lens, while a plurality of one-to-one corresponding aperture (female) alignment features are provided in the outer bezel. During the mating, each elastic tube and its respective aperture provide elastic deformation, which, on average, precisely aligns the emblem lens with respect to the outer bezel.
