Claim 10:
11. An aircraft position light assembly, comprising:
a housing having a lens mounted thereon;
an infrared light emitting diode (IRLED) mounted within the housing, the IRLED operable to emit IR light at an emission intensity toward the lens;
a plurality of non-IR LEDs mounted within the housing and spaced apart from the IR LED, each of non-IR LEDs operable to emit visible light in a direction away from the lens; and
a hemispherical dome mounted within the housing between the IRLED and the lens, the hemispherical dome comprising a material that attenuates the emission intensity by a predetermined magnitude, the hemispherical dome having an apex and an axis of symmetry that extends through the apex, and further having an aperture formed therein and through which a portion of the IR light emitted from the IRLED may pass unattenuated, the aperture disposed at a predetermined angle relative to the axis of symmetry.
