Looks like a great setup! I just checked out the Eurowise bar but unfortunately with shipping to New Zealand, it works out at just under $1000 in our money - which is more than the price of the LED lights I'm looking at.
I drive a lot on very dark country roads and the factory HID high beams in my 2012 V8 TDi seem to be quite rubbish - I'm looking at a good quality pair of auxilliary lights (1 x spot, 1 x flood) to light up the road (and sides) a good distance ahead of me. My current lights are so bad that people often don't even flash me when I'm on high beam.
We also tend to get some good sized wildlife stepping out in front of us from time to time (deer, cattle, sheep, wallabies) and with the current lights I've had a few close calls because I almost don't see them in time. Lighting up the sides of the road with the flood beam will definitely help with that, along with generally being able to see further up the road.
