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.
I bought these thinking that they might be cheaply made, but I was really surprised. Instead, I read on the box that they were made in Germany; hence, the reason for the high quality. If you buy these wheel center caps, you will not be disappointed. They are very high-quality.
