The things are pretty pointless anyway ( imo). I drove the entire west coast route from France to Spain, in daylight and night. It was bug soup, some of them must wear Kevlar because they hit the screen with a bang and spread glup. I was using the wash/ wipe a lot and kept the screen clear. When I parked up I looked at the headlamps they were thick with impacted bugs etc. The wash facility had made no difference at all to the headlights apart from giving them a warm bath. I had a Beemer years ago and that had cute little wipers that worked with the headlamp wash... must have been better. Why didnt LR think of that?
