  We revisit the alternative left-right symmetric model, motivated by
superstring-inspired $E_6$ model. We systematically analyze the constraints
imposed by theoretical and experimental bounds on the parameter space of this
class of models. We perform a comprehensive analysis of the Higgs sector and
show that three neutral CP-even and two CP-odd Higgs bosons in addition to two
charged Higgs bosons can be light, of ${\cal O}(100)$ GeV.
  We emphasise that our model has a potential to account for the recent Large
Hadron Collider results for signal strength of Higgs decays. We also explore
discovery signatures of the exotic down-type quark, which is one of the salient
predictions of this model.
