So the question is this, is light an independent entity or is it somehow an observed effect of a larger mechanism.It all depends what level you are talking about. Clearly, light is just a part of the overall electromagnetic spectrum, which is an effect of oscillating electric/magnetic fields. So you would say that light is an observed effect of the laws of electromagnetism. Remember, Einsteinís first paper on relativity dealt with a specific problem in electrodynamics (moving electromagnetic fields) that had been puzzling scientists; it was in that paper where he suggested light does not behave as if propagated in a medium so itís measured speed is not affected by the emitter or observer. This speed also comes from Maxwellís equations which are based on the findings of Amper, Faraday, Coulomb and Gauss - all leaders in electromagnetic theory.
