The following code snippet will read the current Blender scene and extract any selected Blender Light that has a label starting with 'Nightlight'. In the current form, you will need to copy the output from the Console (see Using Blender's Console in above list) and paste it into a external SCN file. Use a Blender Point Light to represent rFactor's Omni light. The Point Light controls provide the appropriate values for rFactor's Omni light. The following has been tested in 2.8+.

    
    # Output must look like this::::
    #   Light=Nightlight00
    #   {
    #     Type=Omni Pos=(-384.0, -20.0, -143.0) Range=(0.000000, 76.000000) Active=True Intensity=(1.000000) Color=(255, 255, 255)
    #   }

    # Type=Omni   :: rFactor's 'Omni' is Blender's 'Point', must make the change before writing out the file
    # Pos=()      :: rFactor's 'Pos' is Blender's 'location'
    # Range=()    :: rFactor's 'Range' param 2 is Blender's 'distance' - not sure what param 1 is
    # Active=     :: no Blender equivilent --- but True is assumed
    # Intensity=():: rFactor's 'Intensity' is Blender's 'energy'
    # Color=()    :: rFactor's 'Color' is Blender's 'color', BUT Blender's values are normalized 0.0 to 1.0;; rFactor's is 0 to 255, MUST CONVERT

    import bpy

    for selectedLamp in bpy.data.lights:
        rf_type = 'Not Found'
        lampName = selectedLamp.name
        
        if lampName.startswith('Nightlight'):
            rf_type = 'Omni'

        rf_Intensity = "{:.6f}".format(bpy.data.lights[lampName].energy)
