By law, at any time - day or night, when driving in Europe you must convert your headlamps to avoid dazzling other road users.
UK Vehicle headlamps are specifically designed for driving on the left hand side of the road. Consequently, when driving on the right in Europe your headlamps will shine into oncoming traffic. This will severely dazzle other road users, is dangerous, illegal, and must be prevented at all times - night or day (including, rain, fog, etc.). Before driving on the continent, always ensure your vehicle is LEGALLY FIT FOR THE ROAD by adapting your headlamps...
Most of the adaptors are easy to fit and supplied with individual fitting instructions for the latest 'Clear Glass', 'Projector' and 'Xenon / HID’ headlamps, along with instructions for the earlier 'Glass Line Patterned' headlamps.
