Some versions of superstring inspired models have vector leptons, which decay only through their suppressed mixing with ordinary leptons. The striking signals of an opposite sign dilepton and a pair of weak gauge bosons (ll-bar WZ, ll-bar WW and ll-bar ZZ) from such vector leptons produced at the SSC are examined. The authors find that the mass degenerate pair of charged and neutral leptons will be observable at the SSC if they are lighter than a few TeV.
