Figure 14 shows the practical circuit of a transistor two led flasher which can be converted to single led operation by simply replacing the unwanted led with a short circuit.
12v dc led flasher circuit diagram.
This is a small size led flasher built with the 555 timer ic that is powered from 2.
Led current in amps 1 25 r3 so for a current of 550ma set r3 to 2 2 ohms you ll need a power resistor usually r3 power in watts 1 56 r3 this circuit also has the drawback that the only way to use it with a micro controller or pwm is to turn the entire thing on and off with a power fet.
Hope for your response.
