Airport Highway Sequenced Timed Lights Circuit

I am a beginer in electrical engineering, and I wanted to make in my home yard a timed flashing sequence of lights just like in Airports (like in the photo) but I don't know how to do it. The walk route is long 15 meters!
I saw some examples with 555 with small LEDs but in my case the lights are for outdoor environments with different voltages!
I need an answer as fast as possible,PLEASE!!
Thank you!

Well, with the examples you saw with 555 timers, generally the concept is just the same just with a higher voltage in mind. Also the controller part is on a much larger scale. Now, the big question is how to do it, right? First, the arduino can still work as your controller but the output must be step-up to enable the LED to function. Second, you should know the total power needed by the whole system.

Thank you for the replay but the :
CD 4017 is a divide-by-10 CMOS chip.
Minimum supply voltage 6v
Maximum supply voltage 15v
Max current per output 15mA
Maximum speed of operation 5MHz and the :

555 timer

Supply voltage (VCC) 4.5 to 15 V
Supply current (VCC = +5 V) 3 to 6 mA
Supply current (VCC = +15 V) 10 to 15 mA
Output current (maximum) 200 mA
Maximum Power dissipation 600 mW
Power consumption (minimum operating) 30 mW@5V, 225 mW@15V

VOLTAGES ARE VERY LOW COMPARED WITH THE POWER NEEDED FOR THE IN-GROUND LED LIGHTS!

Can you find me a solution,please!
