1. A lighting apparatus for a mobile machine, comprising:
a blue laser diode device comprising a gallium and nitrogen containing material configured to emit electromagnetic radiation having a wavelength ranging from about 400 nm to 500 nm and having a beam spot size to create an output beam of the blue laser diode device;
a phosphor material configured to interact with the output beam of the blue laser diode device to generate a white light output of electromagnetic radiation characterized by an output of 400 to 2500 lumens and 500 Candela per square millimeter and greater;
a surface mount substrate configured to attach the blue laser diode device on a surface of the surface mount substrate;
a window or lens device operably coupled to the white light output of electromagnetic radiation and configured to focus and spread the white light output of electromagnetic radiation to cause formation of a white light beam;
an infrared laser diode device configured to output electromagnetic radiation having a wavelength ranging from 800 nm to 1800 nm and having an output beam to create an infrared output beam;
an electronic control unit configured to operate the blue laser diode device independent from the infrared laser diode device;
wherein the white light beam is configured for at least one of a high beam application, a low beam application, a low beam cut application, or a high beam spot application; and
wherein the window or lens device is arranged so that the white light output of electromagnetic radiation and the infrared output beam propagate through the window or lens device colinearly.
