  If the Standard Model is embedded in a left-right symmetric gauge theory at
the TeV scale, the pair production of light W-bosons in e^+e^- collisions,
e^+e^- -> W^+W^-, will be affected by mixings in the gauge and neutrino
sectors, and by the t-channel exchange of a heavy right-handed neutrino. The
modification of the cross section by these new effects is studied for
high--energy e^+e^- colliders.
