A multi-mode visible and infrared lighthead ( 100 ) for use as a landing light or searchlight. The multi-mode lighthead incorporates a modular design wherein at least one visible light source ( 200 ) and at least one infrared diode ( 302 ) are mounted into the rear sector ( 128 ) of a housing ( 102 ). Visible or infrared light is emitted out of the front sector ( 122 ) of the housing ( 102 ). Lenses ( 308 ) are installed onto the front sector ( 122 ) of the housing ( 102 ) and sealed to protect the interior of the lighthead ( 100 ) from the elements. Alternatively, and in combination, an imaging module ( 1 ), and infrared laser ( 400 ) and/or a fixed-position searchlight with rangefinder and positioning capability is provided in the multi-mode lighthead( 100 ).
