[Also in Division H3] A circuit for lighting lamps in sequence comprises a plurality of regenerative static amplifier pairs coupled by time constant circuits and each feeding a lamp. The circuit is suitable for use in direction indicators for cars, guide directional lights for vehicles or aeroplanes or for advertising. When supply switch 2 is operated the regenerative complementary transistor circuit 4 1  6 1  is rendered highly conductive by current through resistor 7. Current in the circuit energizes lamp 12 1  and charges a capacitor 11 1 . When the capacitor voltage reaches the threshold voltage of circuit 4 2 , 6 2  this also becomes conductive, switching on lamp 12 2  and initiating the charging of capacitor 11 2 . Successive lamps are accordingly lit until circuit 4n, 6n becomes conductive. This, through rectifier 14 1  raises the emitter potential of transistors 6 1 -6n-1 and switches the circuits off. When capacitor 16 restores circuit 4n, 6n to its non-conductive state the switching sequence repeats. In a similar circuit (Fig. 1, not shown) repetition of the sequence is initiated by opening automatically an electronic switch (5) in the supply line to the emitters of transistors 6.
