This page features a replacement circuit for the LM3909 LED Flasher / Oscillator using discrete components. The circuit is functionally the same as the integrated LM3909 but has a minor variations in values of the components used. If you like to use the integrated circuit LM3909 build be Flasher Circuit. But may get into trouble about apply to Lamp at have the requirement Current tall no. I then introduce to see this circuit can apply to power supply 3V and apply to Lamp 3V 1A get
