Both of the front headlight trims came with one having the letter "A" and one having the letter "B" but does not instruct on which one is left and right side. Both pieces are almost identical and fit nearly the same on either headlight trim. I feel that there should be some sort of instruction on which one goes on the left or right side.
I got this light for my R53 Cooper S and the plug in for the harness did not fit the harness in the car. I needed to modify the circuit board and change the wiring harness in my car so that it would fit.
These look FANTASTIC on my 2015 MINI Cooper S COUNTRYMAN. The all chrome design goes Great with my chrome fender scuttles. Very happy I bought them.
