I thought that Euro4 was about emissions. You have got me going now, I shall have to see if I can find out.I thought it came in with Euro 4
That will probably be the glue neoprene glue. While new it will be easy to remove that residue, but after a while it will be difficult to remove. As neoprene is acetone based, a quick wipe with a cloth and acetone will remove even old residue. If you cannot find acetone, then use the wife's nail varnish remover as it is acetone.Just pulled them off by hand. They come off easy. Backing is a rubberized sticky stuff. No residue left over.
I searched all over the net about my local law regarding the side reflectors. I even went as far as making a visit to the traffic department, even the traffic cops didn't know if they were required on the sides anymore. The old law was white on front, amber on sides and red on rear. The rear remains but I pulled the sides off now.Well I was cleaning it again today and noticed both reflectors were loose. They would have both fallen off if I hadn't removed them, literally just hanging off.
