I think this is by design (stupid if so) When I have the main beam on, drive on a country lane and put my full beam on, the mains turn off, resulting in quite poor visibility to be honest. If my mains are on and I flash the full they all stay on. So what I end up doing is holding the stalk in such a way I get both main and full. Is it working how it should be or buggered? My passat, both stay on but I've got h7 bulbs
