The Dynamic LED wing mirror indicators fitted and work perfectly. I love the look of them. The lens glass (plastic) is smoked which looks really good on a black wing mirror casing. There's no instructions in the packaging, but there's a couple of very good YouTube videos which are easy to follow. The kit comes complete with the tool for removing the wing mirror glass and the special Torx key which you need dismantle and reassemble the wing mirror. It took me approx 20 mins to fit the new indicators.
