XBB Dongle® & XBB PowerUnit® – XBB System

At some point I'd like to add some extra lighting to the front of my car and have it triggered by the high beam.
The linked device above appears to give that high beam trigger with no loom modification.
The high beam lights on my formentor are ok but not XXX mph on a pitch black road in the sticks ok.
Re insurance + mot's I have done this previously with my 2015 macan which had filament high beams I could draw a direct switched feed from. the light bar was declared to the insurance co who were fine with it and 3 different MOT places said as it was on high beam only and worked that was all that was required.
