So just to clarify for your car then:
A: DRL only - one light in each unit at the front, nothing else (this comes from either an LED strip running along the bottom of each unit, or a bulb inside it).
B: Sidelights - same as the DRL above (if it's the LED strip running along the bottom of each unit then it will be dimmer in this position than in A, if it's a bulb then I'm not sure as mine is the LED strip) plus the tail lights, license plate lights and all the interior ones.
C: Headlights - exactly the same as B with the addition of the dipped bulbs, one in each unit at the front.
Then there's the full beam which is another bulb in each front unit, and the front and rear fog lights too.
Hope this clarifies things!
