Using this circuit the lamps glow in sequence in a speed given by the capacitors. The SCRs present a voltage fall of about 2 V. This can be considered when powering the circuit. The capacitors must range from 1 to 100 µF. This circuit turns-on the lamps only one cycle. After all lamp glow up the circuit must be reset turning of by a moment the supply.
