I think that i might have a dodgy light switch. I normally keep them on auto, but needed the fogs on. I clicked it round to the dipped headlamps logo and pulled the switch out. Fair enough, they come on. But, the switch wont push back in and stay in to turn them off. So, i have to turn the switch back to one of the other positions before i can push the switch back in to turn them off. Trouble is it also turns the headlights off as well momentarily ! Yes, i've read the handbook, which covers turning them on, but not off!
