So, you have several options/combinations of DRLs you can set up. For example, you can run headlights only, foglights only, turn signal and sidelights only or a combination thereof. It all depends on which you prefer. There is also the option that turns off a DRL when the corresponding turn signal is activated. For example, if you're running your headlights as DRL, activating the right turn signal will drop out the right headlight.
