Light, Light-Source, Speed of Light

That the Speed of Light is independent of the velocity of a light-source, whether natural or manufactured, does not entail that Light is independent of a Light-Source.  For, as is plainly observable both inside and outside the Physicist's laboratory, no matter what the conditions, Light is located at a Source, e. g. at a bulb, as well as wherever else it emanates to.  Now, according to established formulae, the Length of an object contracts to Zero as it approaches the Speed of Light; in other words, it becomes a Plane.  But, it seems difficult, at best, to conceive of a body or device becoming a Plane, and still functioning as a Light-Source, in which case, Light ceases to exist.  Thus, the existence of Light is dependent on not only the existence of a Light-Source, but of its velocity, as well.
