Push the button and they'll come on as long as the vehicle is running and in drive (or any forward gear).
They do not come on while in park. If they don't come on, you need to push the button on again. A quick trick to see if they're working is in a non-traffic area only put on the parking lights and the foglights will come on when you shift into drive as long as you've pushed the button on the turn dial.
You did push the turn-dial, correct, not the rear bed-cargo light, correct?
