If properly understand the nature of light, the traffic light will obey the fundamental laws of physics (aerodynamics).
The article ON INVARIANT LIGHT (see
http://advancejournals.org/journals/Manuscript/327/ON-INVARIANT-LIGHT ) shows a model of the origin of light and the path of motion. It is based on the vortex theory of gravity. That is, the atoms are created micro vortices of ether. The speed of the ether by several orders of magnitude greater than the speed of light. Near the surface of the atom atomic force of gravity reaches huge values and pressure of the air is converted into electromagnetic flux, including in the light. With increasing mass, the light slows down their movement and speed to become equal to a constant - S. the Speed of light is the cosmic speed up until the atomic force of gravity will be equal to the centripetal force. When the effects of the substance (heated), and consequently the atom, atomic force of gravity decreases and the speed of light becomes the escape velocity. Light is removed from the atom by the spiral, the most economical path. This trajectory in the 40-ies of the calculated Homan. The huge number of atoms and the number of light micro-flows and their orbits, the same is enormous. Thus, the light comes on any object from all sides with its constant velocity. If the object is moving, its motion is always perpendicular to the motion of the main flow of light. According to the laws of vector algebra speed of light can't be folded with the movement of other objects, since they are mainly directed perpendicular.
As the movement of light can be explained by the fundamental laws of physics, the light has not paradoxical properties - invariance and isotropy. Therefore special relativity - an absurd hypothesis.
