Just realised a cool feature with these. They light up not only when you turn the wheel but also when you indicate, ie before you start to actually turn. Very clever, and useful.
Even better, if you get the Xenon headlights, not only are they adaptive and swivel to follow the bends in the road, but for slow tight turns, there is a dedicated cornering light in the headlight unit that actually faces sideways (rather than straight ahead), and really gives massive illumination to the side of the road.
