They do look weird on that image although that is the indicator and they are a ribbed glass that is not perfectly clear. (No misting thankfully)

I've been laying out on the driveway putting dollops of polish onto the wheels. My intention was to take the wheels off, but when my son started to use the supplied jack, one of the welds broke. The vehicle is now just five years old, but the jack has never been used. I had a word with the dealer (who has only been in business for a couple of years) and they are sending me a free replacement.
