In the framework of gauge-invariant effective Lagrangians the resulting changes in Higgs boson production and decay mechanisms are related to anomalous triple vector boson couplings. Using low energy constraints on the dimension-six operators in the effective Lagrangian, we discuss the size of deviations from SM predictions which may be expected in Higgs boson production and decay rates. Large enhancements are allowed {\it e.g.} in the $Z \to H γ$ and $H\to γγ$ partial decay widths, leading to $Z\to γγγ$ events at LEP.14 pages. Uses RevTEX.
