This is used to light certain objects in the scene selectively.
A GameObject will only be illuminated by a light if that light's cullingMask includes the layer chosen for the GameObject (ie, the mask bit for the layer must be set to 1 for the object to receive any light). See Layers for more information about layer masking. See Also: Light component.
// Only light objects in the first layer (Default layer)
light.cullingMask = 1 << 0;
