EDC warning light on MAN LE150C (D 0824 LFL engine)

AF1:
Check all the right hand flasher bulbs work as that’s the tell tale to let you know when a bulb blows.

Hmmmm. I count three flashing bulbs on the right - the same number as on the left.

There’s one near the headlights, one in the tail cluster, and one between the cab and the body.

What am I missing?
