Urgent help

Hi guys

I´m new on this and i have to finish this until tomorrow.
The problem is that i don´t know where i have to put a counter to count 4 cicles when the traffic light is green, can you help me please?
The counter can be with flip-flop d, flip-flop t or flip-flop jk, what are the best to use asa counter?
Can you show 1 exemple for the image attached?


Many thanks in advance

Please, help me on this...

Wouldn't us doing your homework for you be cheating?

I have done all the things that is needed for this work, i have done the counter, only i just don´t know where to put it.
