1. A light for the exterior of a vehicle, the light comprising:
at least one illuminant; and
a light disk,
wherein, in an activated state of the illuminant, the illuminant emits light that hits the light disk directly,
wherein the light disk is transparent to light in a first predetermined wavelength range and reflects light in a second wavelength range when the illuminant is deactivated, wherein the first predetermined wavelength range is different than the second wavelength range,
wherein the illuminant is at least one light-emitting diode (LED), which emits light in a third wavelength range that is predetermined such that the emitted light, after transmission through the light disk, is present in a predetermined fourth wavelength range that is at least different from the second wavelength range, and
wherein the at least one LED emits light in a wavelength range of a cyan-colored light according to a CIE color diagram.
