  Most of the current experimental searches for charged Higgs bosons at the
Large Hadron Collider (LHC) concentrate upon the $tb$ and $\tau\nu$ decay
channels. In the present study, we analyze instead the feasibility of the
bosonic decay channel $W^{\pm *} h$, with the charged gauge boson being
off-shell and $h$ being a neutral light Higgs boson, which decays predominantly
into $b\bar{b}$. We perform a Monte Carlo (MC) analysis for the associate
production of a charged Higgs with such a light neutral one, $pp\to H^\pm h$,
at the LHC followed by the aforementioned charged Higgs boson decay, which
leads to a $W^{\pm *} +4b$ final state. The analysis is performed within the
2-Higgs Doublet Model (2HDM) with Yukawa texture of Type-I. We take into
account all available experimental constraints from LEP, Tevatron and the LHC
as well as the theoretical requirements of self-consistency of this scenario.
In order to study the full process $pp \rightarrow H^{\pm} h \rightarrow W^{\pm
*} h h \rightarrow \ell^\pm \nu+ 4b$ ($\ell=e,\mu$), we provide several
Benchmark Points (BPs) amenable to further analysis, with $M_{H^\pm}+M_{b} <
M_{t}$, for which we prove that there is a strong possibility that this
spectacular signal could be found at the LHC with center of mass energy 14 TeV
and luminosity 300 $\rm{fb}^{-1}$.
