2009 S80 Headlight question

[fxral]

Just bought 2009 S80 with the active dual xenon option.
It appears that the Rt headlight is missing the 2 modules mounted on the bottom of the headlight assy. 
The hi beam works but  not the lo beam.My question is - do I need both modules for the lo beam to work?
Looking online the ballast control module is relatively inexpensive whereas the control unit runs a few $. 
I'm more interested in getting the lo beam working,could live without the active feature.
Also odd that most listings are across the pond.?
Appreciate any help/suggestions.
Thank you

Hey! How's your research so far? We'll take a look at this S80 with a similar issue. The low beam doesn't work for most of the time and the owner suspects it's the module. We'll take her in this week once we mounted the suspension and shocks from 4Wheelonline onto the Jeep.
