The Ball-of-Light Particle Model predicts a Pulsar is a ball-of-light that has a very powerful electromagnetic wave sweeping across its surface. The pulsar has no outer envelope of material such as the outer plasma envelope of a normal star.

If the Ball-of-Light Particle Model is correct, then the magnetic field orientation of the top and bottom hemispheres in the above graphic should be curling in opposite directions. If the traditional theory of pulsars is correct, then the magnetic fields in the above graphic should be oriented in the same direction. A recent image of the Egg Nebula from the Hubble Space Telescope is shown below.

Notice how the light is polarized in opposite directions. This matches the Ball-of-Light Particle Model, not traditional theory.
