Abstract
A vehicle lamp has at least one transparent element (), and at least one main light source, whose emitted light passes the optical boundary layers of the at least one transparent element () substantially perpendicularly. The at least one transparent element () has at least two optical areas () with different optical indices of refraction which adjoin one another along at least one optical boundary layer (), and at least in one of the adjoining optical areas (), whose index of refraction is greater than the index of refraction of the adjoining optical area (), the light of at least one light source is coupled via at least one light coupling point () into a direction pointing substantially along the at least one optical boundary layer (), and the introduced light is decoupled via at least one light decoupling point ().
