I agree. They're about as much use as a chocolate fire guard.

However, they are a statutory requirement throughout Europe wherever xenon lights are fitted, so those of us with 98 and later have to have them. Actually, my wife's BMW doesn't have a headlamp cleaning system and after a few days driving at this time of year, the lighting is much diminished.
