Definition: The .0110_phys_lightsgreen.conf file contains a configuration for setting up light green lights, but it doesn't seem to contain a specific information about a physical light source named 'PhysLightGreen'. This might be due to a typo in the name or the file path. For more accurate information, you would need to provide the exact location of this .conf file within your system's configuration directory or check if there are any external references that may help understand its purpose.
