  We examine multiphoton production in the electroweak sector of the Standard
Model in the high energy limit using the equivalence theorem in combination
with spinor helicity techniques. We utilize currents consisting of a charged
scalar, spinor, or vector line that radiates $n$ photons. Only one end of the
charged line is off shell in these currents, which are known for the cases of
like-helicity and one unlike-helicity photons. We obtain a wide variety of
helicity amplitudes for processes involving two pairs of charged particles by
considering combinations of four currents. We examine the situation with
respect to currents which have both ends of the charged line off-shell, and
present solutions for the case of like-helicity photons. These new currents may
be combined with two of the original currents to produce additional amplitudes
involving Higgs, longitudinal $Z$ or neutrino pairs.
