Abstract: A dual mode visible and infrared lighthead (100) for use as a landing light or searchlight. The dual 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 housing (102) and sealed to protect the interior of the lighthead (100) from the elements.
