  We investigate the potential collider signatures of singly-charged and
doubly-charged Higgs bosons such as those arising in minimal left-right
symmetric models. Focusing on multileptonic probes in the context of the
high-luminosity run of the Large Hadron Collider, we separately assess the
advantages of the four-leptonic and trileptonic final states for a
representative benchmark setup designed by considering a large set of
experimental constraints. Our study establishes possibilities of identifying
singly-charged and doubly-charged scalars at the Large Hadron Collider with a
large significance, for luminosity goals expected to be reached during the
high-luminosity phase of the Large Hadron Collider. We generalise our results
and demonstrate that existing limits can in principle be pushed much further in
the heavy mass regime.
