Abstract
A control circuit for direction indicator lamps of a vehicle includes an alternating voltage generator suitable for feeding the lamps through a manual commutator or switch and at least one bi-directional conduction controlled diode which is driven by an impulse generator. The latter is suitably driven by the alternating voltage of the generator to furnish an output signal of alternating impulses synchronized with the zero changeovers of the alternating voltage. The impulse generator is driven by a timing stage with a signal of alternating blocking and admitting impulses.
