Tail Light Sequencer

Found the attached circuit in the experiments section. How can I modify the circuit to create a right turn signal (of course would mirror it for the left turn signal). Using only three LEDs.

To show the turning direction, by turning on three LEDs in sequence (no lights; inner light; inner two lights; all three lights; repeat).

There is also an emergency flasher mode, HAZARD, that requires all six lights, on; then all six lights off; repeat).

The inputs are to be implemented using push button switches and the outputs with LEDs. I would use two push buttons switches to select, LEFT or RIGHT turning and a third push button switch for the hazard light.

 

Sorry Mate. Modifying vehicle lights is against regulation.
