Incandescent Lamp Flasher (CB1393E)

This circuit, for a bulb of 6 V up to 200 mA, was found in an old Argentine publication of the 1970s. We can currently mount it with a BC548 for Q1 and BD136 for Q2. The capacitor determines the frequency of the blinks and R1 its duration. The circuit can be changed to operate with 12 V, simply change the lamp.
