We were waiting in line at the Drive-Thru at CVS Pharmacy, at the weekend, here in Indiana, USA, when I spotted that the vehicle in front of us had one tail light half full of water. It slopped around whenever the vehicle moved. The vehicle was a Toyota 4Runner, with a rusted out back bumper. Unfortunately, I did not snap a picture of it. The picture above is one I found on the web, for illustrative purposes.
That brought back memories of seeing the same thing, back in the UK, in the late 1970s or early 1980s. I have been wracking my brains, trying to remember which type of vehicle used to collect water like that. I think one of my cars did that, so I think it was a Ford Escort Estate. It must have had a bad seal at the top, letting in water, which could not escape. I kind of remember one cheap cure was to drill a small hole, in the bottom, to let the water escape.
