While you can order the driving lights with the car so they get installed at the port, it is not necessary and because they are accessories, they can be installed anytime. The process is the same whether they get installed at the port or at the dealer months down the line.The LED Driving (i.e. Rally) Lights need to be ordered with the car. I was told they wire the car for them when manufactured with a separate toggle, so you cannot add them later without it not being a factory look. They are installed at the port of entry (or at the dealer).
