I bought a set of beam deflectors when I first started driving in Europe, I do about 60,000 miles on the continent each year, have done in succesive roles and succesive vehicles since 1985. First as a Trucker, then a distibution Manager, then a Sales rep, then a courier, then a Trucker again, and for the last 11 years an Exhibition contractor.
Also holidays in a car/4X4/motorhome.
Never fitted them, still in the tool bag just incase.
