I'm starting to understand that this is all a whole lot more 'complicated' than my simple mind was prepared for. Having only recently picked my R1200RT up, & not having been able to make sense of what the Owner's Manual seemed to be saying, what I've read here is shedding more light in what I couldn't (still can't at this point) figure out.
The DRL's on her seem to have a mind of their own. When set to Auto they appear to do some freaky things, most of which I can't see from the seat.
Quite by accident, during a carpark encounter with an idiot who failed to check his rear view mirror prior to attempting to reverse over me while I was pulling into a parking space, I discovered that she has some kind of 'two stage' horn, which starts off as something akin to the horn of a reasonable size car but then steps up to something like a train horn if the hirn bitton is pressed down for more than a couple of moments. I don't know what the DRL's get up to when this happens, however, I think I perhaps need to investigate this further.
Until now I hadn't put all of this together, but from what I'm reading here it appears that she may be fitted with a 'Danali' or similar system, which I reckon is a good thing, once I figure out how to work it all.
What brought me here was the pursuit of knowledge of how the DRL's 'work'; what replacements are available for the lights that are currently on her, which are looking tired & appear to be a composite of conventional globes & LED's; & the best options for installing 'driving lights', as we have a variety of Komakazi wildlife & livestock roaming our local roads, which I'd prefer to avoid getting too close to. The best option to avoid said beasties is to avoid riding these roads between dusk & dawn, however, there are limited alternatives if one gets held up along the way, as there is pretty much nothing in the way of accommodation, etc. for hundreds of kilometres between road houses &/or towns.
Hopefully someone out there can give me some guidance, please.

I've added some pics of the RDL's currently on my baby. I haven't been able to find anything similar but fully LED thus far.
