it is to build a LED wig wag flasher using just a couple of transistors and few
other passive components. A LED flasher schematic has also been provided to
facilitate the ease of construction.

The circuit of a simple LED wig wag flasher presented here incorporates
just a couple of transistor and is wired as a multivibrator. The transistors
alternately switch the LEDs connected to their collector points to produce an
attractive flashing effect of LEDs. The circuit may also be used as an LED emergency flasher unit.

construction of this LED flasher is very simple and is finished through the
following simple steps:
two transistors somewhere around the centre of the board. Keep at least an inch
of space in between them.
