    gekennzeichnet durch ein erstes lichtemittierendes Element (2), das den ersten Lichteintrittsflächen (121) zugewandt ist, wobei sich ein erster Lichtstrahl, der von dem ersten lichtemittierenden Element (2) emittiert wird, zunächst in Richtung der optischen Achse (L) durch die ersten Lichteintrittsflächen (121) ausbreitet und dann von den reflektierenden Flächen (111) zu den Lichtaustrittsflächen (113) reflektiert wird;
    wobei die Linsen (1) fest miteinander verbunden sind und entlang der optischen Achse (L) angeordnet sind, die Kopplungsflächen (112) der Linsen (1) aneinander anliegen und die Lichtaustrittsflächen (113) der Linsen (1) voneinander weg weisen.
  2. Transparente Fahrzeugleuchte nach Anspruch 1, ferner dadurch gekennzeichnet, dass jede der Lichtaustrittsflächen (113) der Linsen (1) eine konvexe Linse ist.
  3. Transparente Fahrzeugleuchte nach Anspruch 1, gekennzeichnet durch eine Schale (4), die die Linsen (1) aufnimmt und einen umgebenden Abschnitt (41) aufweist, der den ersten Lichteintrittsabschnitt (12) und das erste lichtemittierende Element (2) vollständig abdeckt.
  4. Transparente Fahrzeugleuchte nach Anspruch 1, ferner dadurch gekennzeichnet, dass für jede der Linsen (1) die reflektierende Oberfläche (111) mehrere gekrümmte reflektierende Oberflächenteile (114) aufweist, die in Richtung der Lichtaustrittsfläche (113) vorstehen.
  5. Transparente Fahrzeugleuchte nach Anspruch 1, ferner dadurch gekennzeichnet, dass
    jede der Linsen (1) ferner einen zweiten Lichteingangsabschnitt (13) aufweist, der mit der anderen der gegenüberliegenden Seiten des Hauptkörperabschnitts (11) verbunden ist, von dem ersten Lichteingangsabschnitt (12) und der optischen Achse (L) beabstandet ist und eine zweite Lichteingangsfläche (131) aufweist; und die transparente Fahrzeugleuchte ferner ein zweites lichtemittierendes Element (3) aufweist, wobei für jede der Linsen (1) ein zweiter Lichtstrahl, der von dem zweiten lichtemittierenden Element (3) emittiert wird, sich zunächst in Richtung der optischen Achse (L) durch die zweiten Lichteingangsflächen (131) ausbreitet und dann von den reflektierenden Flächen (111) in Richtung der Lichtausgangsflächen (113) reflektiert wird.
