Need help for designing circuit for LEDs of car

[moonnightingale]

I want to simulate a circuit of car in a software. There are three lights on each side of a car. when the car is given instruction to turn, these lights operate in a sequence. First of all inner light then inner two and then inner three and this procedure is repeated. For both right turn and left turn it follows this procedure.
There is also a emergency input (Hazard light) which flashes all six LEDs as on/off/on and so one
I have to design a sequential circuit for above stated
Can u tell me the components which will be used for this circuit
Thanks

I am using 4017 IC but this IC swiches on only one LED at a time
what i need that first LED glow, then first two and than all three for the turn
which IC i should use
