Aircraft tail navigation light, aircraft comprising an aircraft tail navigation light, and method of operating an aircraft tail navigation light

An aircraft tail navigation light, comprising:

• a navigation lighting assembly for emitting a regular navigation light output;
• and
• an orientation lighting assembly for emitting an orientation light output;
• wherein the aircraft tail navigation light is switchable between emitting the regular navigation light output having a navigation light intensity and emitting the orientation light output having an orientation light intensity;
• wherein the navigation light intensity is larger than the orientation light intensity;
• wherein the orientation lighting assembly comprises at least one orientation light source and an orientation light output diluting element, which is arranged over the at least one orientation light source for shaping the orientation light output from light emitted by the at least one orientation light source;
• wherein the orientation light output diluting element comprises a light sieve, and
• wherein the light sieve comprises light blocking barrier portions and light passing portions.
