This disclosure relates to a commutating circuit for alternately fully energizing a first load and a second load for use in highway crossing warning applications. Associatively connected to the first and second loads are first and second gates through first and second windings of a commutating transformer, respectively. A source of gating alternately triggers the first and second gates to fully energize the load associated therewith. The commutating transformer alternately disables the first and second gates; thereby alternately substantially deenergizing the first and second loads.
