Citroen C3 Picasso Dipped Headlights

[R1Mark]

My dad recently asked me to look at his car as one of the driver side dipped headlights stopped working. We changed the bulb assuming it was a blown bulb which didn't fix it. Swapped bulbs over from passenger side to prove all bulbs were healthy. I checked all fuses in the engine bay fuse box and all were fine.

Does anyone know if there a relay associated with the dipped headlight function? If so where is it located?

Thanks in advance
