General expressions for one-loop contributions associated with lepton-flavor violating decays of the standard model-like Higgs boson $h \to e_b^\pm e_a^\mp$ and gauge boson $Z \to e_b^\pm e_a^\mp$ are introduced in the unitary gauge. The results are used to discuss these decays as new physics signals in a minimal left-right symmetric model containing only one bidoublet Higgs and a $SU(2)_R$ Higgs doublet accommodating data of neutrino oscillations and $\left(g-2\right)_\mu$ . The numerical investigation indicates that some of these decay rates can reach near future experimental sensitivities.
