if you connect the 2 driver transistors to 3 4017 pins (not 2) the lights will be on for 3 periods.
Then add just 2 diodes, each from the 555 output to the base of one driver transistor.
So the 4017 is used for sequencing, and the lights flash at the 555 rate.
Then you get 3 left flashes, followed by 3 right flashes and it only needs 2 diodes more than your circuit.

No 555 is going to turn off a transistor via a gating diode.
Here is my circuit to stop all the jumping around with descriptions that don't make any sense.
The point to note here is the fact that you described a circuit without actually building it. I learnt not to try that trick, 40 years ago when I suggested a frequency-to-voltage converter without having actually built it.

Both of my circuits flash each LED 3 times. You can adjust the dual 555 circuit to produce the exact flash-rate, and effect, you desire.

Hi marvel6869,
you can use either circuit for 9V.
Just adapt the LED current limiting resistor values accordingly.

CAN ANY ONE HELP ME I WANT TO BUILD A POLICE LIKE FLASHER THAT FLASHES 3TIME ON LEFT AND 3TIME FLASH ON THE RIGHT?
This circuit will not work:
