I keep getting flashed too and have always wondered if they need adjusting. I got flashed by someone the other day that also flashed me last week so it must be a hobby of his!
I had another Edition 30 go past me the other way on the same trip I've just mentioned and his were really bright too. As I do quite a lot of driving in the dark (especially winter time) I get annoyed with people flashing me when my car is as it came out of the factory! I get flashed a LOT more than when I had my Mk 4 R32 with xenons.
