Hi Can anyone tell me if it is possible to adjust the direction of the headlight beam for driving in Europe or do I have to stick those light deflectors onto the lights? I travel to France with work every couple of months and so it would be great if they could be adjusted each time. The manual does not make it clear, it says take the car to nearest dealer. It is a 2007 Vectra CDTi SRI hatchback with standard lights. Any help appreciated. Sean
