Hey, folks. This is getting too emotional. We're just talking about lights.
A useful capability? We've discussed this a lot here in the past, and we'll never reach agreement since we're all using our own subjective criteria. Me, I like the idea for use in twisty woodland roads where I want to see far ahead on the straightaways to avoid the moose, but see what I'm getting into in the few feet in front of me as I round the corners. I haven't actually made this mod yet, but it's on my list to do as part of a total rewiring of the whole front lighting. And there'll be a switch in there to make things legal come time for the annual inspection.
Ticket? Come now, no cop is ever going to observe something this inconspicuous.
I once had a US spec Audi that retained some of its original German wiring. This included the circuitry for cornering lights. With a couple of relays and a bit of wire I set up the fogs so that one side would come on when the blinker for that side was on. It was useful. That was when I lived in a state with no annual inspection!
