  We present a novel study of the non-abelian vector dark matter candidate
$W^\prime$ with a MeV$-$GeV low mass range, accompanied by a dark photon
$A^\prime$ and a dark $Z^\prime$ of similar masses in the context of a
simplified gauged two-Higgs-doublet model. The model is scrutinized by taking
into account various experimental constraints including dark photon searches,
electroweak precision data, relic density of dark matter together with its
direct and indirect searches, mono-jet and Higgs collider physics from LHC. The
viable parameter space of the model consistent with all experimental and
theoretical constraints is exhibited. While a dark $Z^\prime$ can be the
dominant contribution in the relic density due to resonant annihilation of dark
matter, a dark photon is crucial to dark matter direct detection. We
demonstrate that the parameter space can be further probed in the near future
by sub-GeV dark matter experiments like CDEX, NEWS-G and SuperCDMS.
