Claim 0:
1. An aircraft headlight comprising:
a plurality of light emission units arranged in a side-by-side configuration, each of the plurality of light emission units comprising a unit-specific light source and a unit-specific reflector, with each unit-specific reflector comprising a respective central light emitting portion from which a targeted light output of the respective light emission unit is emitted;
and
a light transmissive cover, at least partially covering the plurality of light emission units;
wherein the light transmissive cover comprises:
a first layer made of a first material;
a second layer made of a second material, which differs from the first material; and
at least one electric heating wire for heating the light transmissive cover by passing an electric current through the electric heating wire, wherein the at least one electric heating wire is embedded into the first layer;
wherein outer perimeters of the unit-specific reflectors of the plurality of light emission units have substantially circular projections onto the light transmissive cover; and

wherein the at least one electric heating wire does not extend across the central light emitting portions of the unit-specific reflectors of the plurality of light emission units, and wherein the at least one electric heating wire at least partially extends along the substantially circular projections of the outer perimeters of the unit-specific reflectors and along projections of the interfaces between adjacent light emission units onto the light transmissive.
