I don't believe there were any insults, but maybe my response could have been more friendly.
You're quite right reference dip or main beams though.
If LEDs are used for main only, then yes of course there's no issue to oncoming drivers, unless mains are left on of course.
I've actually tried a couple of makes of LEDs in the mains of my FL1 facelift, but found them really poor at lighting down the road. Close up the light output was good, but lighing distance was much less than the standard H7 bulbs. This is why I went for an LED light bar, which offered huge amounts of extra light, along with enormous range, although those in themselves aren't strictly legal, but as mine was separately switched, it passed the MOT without an issue.
