1. An aircraft light, comprising:
at least one light source for providing an aircraft light output;
a light sensor for detecting a performance level of the aircraft light output; and
a sensor cap, arranged over the light sensor and defining a cavity for accommodating the light sensor, the sensor cap configured to allow a light evaluation portion of a light, emitted by the at least one light source outside the cavity, to pass into the cavity;
the sensor cap having a layered structure comprising:
a cap-shaped support layer;
a first coating layer, wherein the first coating layer is made of a first metal and is arranged on an entirety of an inner side of the cap-shaped support layer; and
a second coating layer, wherein the second coating layer is made of a second metal and is arranged on an entirety of the first coating layer facing the cavity.
