Hella has never offered headlamp relay kits or harnesses (as such), with or without headlamps. They offer relays and accessories (terminals, relay brackets), and they have a few different fog/driving lamp harnesses, but no headlamp relay packages and no headlamp sockets or plugs, etc.
But the 10-years-ago purchase would definitely explain why your original relays were marked Germany. Truth to tell, I steered away from Hella relays about 12 years ago, because even before they moved production to China the comeback rate was too high. Switched to handling Bosch/Tyco and Flosser relays and dead relays pretty much stopped happening.
