2003 ford taurus ses headlights? - 1

So i had a idea of doing this and found this picture. My car is exactly like the picture.
What can i run the LED lights into to where they're on all the time but only when my car is running? I just need ideas of how i can do this?

So you didn't get the hint the first time I answered this so let me help. With the key on you will have power to the coil pack and the fuel injection system. LED lights us so little current it would be no overload on either system. Also the fuel pump and radio.
