The lights work great and look great too. Much brighter than stock. Pretty easy to install after you get the 2 tabs (top & bottom) on the old lights either compressed or just break them as their not need for install or removal there are 3 screws that mount the lights and seal them from the elements.
Replacing the puddle lights on my 2010 R56 with Ringed Mini Wings has been the highlight of my You-ification. There are ridiculously fun to see, as well as being very bright and easy to install. Every Mini should have these!
