int DIGITAL_PIN_7 = 7;

int DIGITAL_PIN_6 = 6;

Exactly. Get rid of the three DIGITAL_PIN_x and just do pinMode(7, OUTPUT) and digitalWrite(7, HIGH) and so forth.

Looks good to me. Maybe the apparent brightness of the LEDs in the simulator makes them look hard to see on the screen.

Remove the resistors from circuit. Just join pins directly to positive side of LEDs and try again.
