This circuit is a low cost easy to build AutoLamps flasher electronic circuit that can substitute the signalization relay or other signalization circuits much expensive .  The heart of this circuit is a 555 timer IC  that works on a fixed oscillation frequency  . This auto lamps signalization electronic circuit can be powered from a 12 volts power supply ( you can use car battery but don’t  connect circuit directly to the car battery ) .  The circuit also offers visual indication for the driver ( the RED Led and GREEN LED must be mounted to offer a visual indication to driver  )  for right side and for the left side  .

You can use this signalization circuit even for other  auto traction machines . The resistor mounted in the emitter of T1 ( AD149 ) must be 1 watt power resistor   .
