Mechanisms for energy supply to the optical bullets are discussed. It is pointed out that in the case of heating by bullet collisions with the system wind, recently shown to be a likely heating candidate, impact polarization of the H-alpha line should be generated. An estimate shows that this line polarization should be at least 0.2 percent and orthogonal to the jet, precessing with it on the sky. This should be observable and is proposed as a diagnostic of the wind heating model, in contrast to turbulent internal heating.
