  We show that a light charged Higgs boson signal via $\tau^\pm\nu$ decay can
be established at the Large Hadron Collider (LHC) also in the case of single
top production. This process complements searches for the same signal in the
case of charged Higgs bosons emerging from $t \bar t$ production. The models
accessible include the Minimal Supersymmetric Standard Model (MSSM) as well a
variety of 2-Higgs Doublet Models (2HDMs). High energies and luminosities are
however required, thereby restricting interest on this mode to the case of the
LHC running at 14 TeV with design configuration.
