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. A two-LED flasher is a simple modification of this circuit, but is arranged so that one LED switches on when the other switches off, or vice versa. I modified the LED count and feedback circuit, and added the important low voltage shutdown feature. The Led dimmer circuit you see in the diagram works like a DC dimmer, the brightness of a number of led groups can be increased or decreased. LED Driver Common Use Product Example Diagram.
