We analyze strong decays of excited charmed and beauty mesons into a lightvector meson, exploiting the effective field theory based on heavy quark (HQ)symmetries for heavy mesons, and on the hidden gauge symmetry to incorporatelight vector mesons. HQ symmetries allow to classify the heavy mesons in spindoublets, and to relate decays of excited states. We build effective Lagrangianterms governing the ${\cal H}_i \to P^{(*)} V$ modes, with ${\cal H}_i$ anexcited $s$, $p$, $d$ and $f$-wave heavy-light quark meson, $P,\,P^*$ thelowest-lying $J^P=(0^-,\,1^-)$ heavy-light mesons, and V a light vector meson.Predictions are provided for ratios of decay widths that are independent of thestrong couplings in the effective Lagrangian terms. A classification of thenewly observed heavy-light mesons is proposed.
