If you take your car from the UK to mainland Europe (or vica versa) then you're required by law to fit headlamp beam adapters[0]. These essentially point both your headlights down to avoid blinding people who are now on the "wrong" side of the road. It does make it lightly harder to see forwards, but avoids blinding other drivers.
